I bought 3 plants at Ziggy's smokeshop in Oklahoma City and the clerk assured me they were all female, but I think 2 of them are male. Pic related is male right? Those are pollen sacks?

Well I never heard of shops selling plants grown out of regular seeds to homegrowers. This could never happen where I am, but then I have two places selling clones within walking distance alone.

If any of these shops would pull that shit they'd won't be around much longer as word gets around quickly.
Maybe OP really got ripped of (which doesn't make much sense from an economic perspective) but maybe he's lying about the "clerk assured me they were all female" part. But then again no shops here will sell plants sprout from landrace sativas, though you can get them as seeds, (we even have seed vending machines, lol) so maybe these are actually regular seed OP bought and they just happen to be male, which, contrary to claims of "high female rate" exactly 12.5% of the time for 3 plants.

Third theory: OP custom ordered plants at the shop, picks them to be grown from landrace sativas and ask the clerk "they are female, right?" when picking them up.
The poor fella, only dealing with people who pick fem seeds doesn't even know the strain and answers "Sure." because what else is he supposed to answer.

OP: If you genuinely were ripped off I am sorry but you gotta admit that this sound highly unusual, perhaps elaborate?

>drive to town B same night
>ask him what strain
"Thai Sticks"
>ask him if they are females
>"yes, we can tell by how far apart the nodes are"

Looking back I should've just bought some feminized hybrid seeds online, but on the bright side I finally have some weed that doesn't put me to sleep instantly and I've made 6 clones of the female plant and let the plant get fertalized so I will have a shitload of seeds as a backup, so life is good. The reason why it cost so much is because basically no stores were even selling plants because the law had just been passed like 2-3 months prior. It all had a happy ending so I'm not about to make a stink. Maybe I'll mention it to him if I ever go back to see if he will give me a free pipe or something.

You can probably keep using the strips and the part of the frame they are attached to.
If you build your own frame about like this picture it might work.

It won't be as good as using Samsung strips with high efficiency (I've got Samsung H inFlux) but should still work fine.

Just keep in mind you need about 400W per sqm (Or about 40W per sqft for the non-metrically inclined) of light.
You can vary that by alot , just be aware of the general rule of thumb figure for optional results.

So, my plants are looking a bit afflicted and I can't seem to find anything that matches the looks of the symptoms exactly.

*It's an outdoor grow
*The plants have been growing healthy and fine up until flowering
*Now the leaves around the bud are curling in odd shapes and directions.

Could be an insect infestation and I'm going to be spreading diatomaceous earth to slow it down while diagnosing.

Anyone see this before?

Hello there fellow green fingered nerds.
Gonna do a loose grow log and hopefully entertain you bunch of degenerates.

This year i'm growing 7 plants. All femenized seeds from a selection of banks.

G13 Haze from barneys farm x3
Jack herrer from greenhouse seeds x1
The church from Greenhouse x1
Cinderella 99, seedbank unknown x2

They popped out of the soil end of april. Using 8ltr water containers for watering, watering each one around 3.4 litres of water daily. Feeding pretty much daily.

Using Hesi neuts and have used the hesi soil neut chart as a rough guide.

They're growing on a roof terrace and I use LST and super topping methods as we have neighbors.

I bought a couple houseplants off of Amazon and this spider plant arrived looking a little sorry for itself. There were some brown leaves and it just didn't look that healthy. It's been 2 weeks and this pic is what it looks like now. Is there anything I can do to nurse this thing back to health?

Do my plants look healthy for 29 days of flowering? (not exactly 29 days, actually - I just switched to 12/12 27 days ago). Also is it OK that dozens of the lower leaves started to wither and fall off since my plants started to bloom? Should I worry about it or it's a natural thing?

Leaves that don't receive any light don't provide photosynthesis though, they're just dead weight. Plus snipping them off gives your plants a little spook, so they'll grow bigger buds because they're afraid of dying.

Kinda fucked up, now that I think about it.

Anyway holy shit OP I thought my first photoperiod grow was going pretty well but god damn I have a tiny shitty dwarf plant compared to your ubermensch stalks. Dang.

True, they're not completely useless. I've gotten high from vaping just van leaves before, not even any sugar leaves. It's a myth that they contain no THC, but they don't contain that much. Probably best to use for cooking. You can blend up the entire plant, then throw it in a crock pot with a few quarts of some water and coconut oil for a few hours then put it in the fridge and scoop up all the solidified coconut oil and throw the rest away.

The plants xylem moves water and nutrients from the roots up into the rest of the plant. The leaves need these nutrients in order to photosynthesize. The phloem moves glucose and amino acids that are produced from the leaves during photosynthesis to other areas of the plant that need them because they are growing like branches, new leaves or flowers. These are both physical passageways and there's a limited amount of space in those passageways. People do stuff like LST and HST (supercropping) in order to widen the stems and widen these passageways so the plant can take up more nutrients and water.

Your lower leaves on a mature plant are the ones that formed earliest, their phloem, the passageways that take the sugars produced by the leaf where they're needed, are connected to the lower branches. Each successive level of leaves during vegetation is connected to the branches that are farther up. Once it comes time for the plant to begin flowering, it puts out leaves that connect their phloem to the flower sites rather than the branches.

Some rerouting of nutrients can be done and the lower branches can contribute some sugars to the lower bud sites, but they will do so extremely inefficiently because the physical passageways simply aren't connected strongly. In order to keep them alive the plant needs to continue to move water and nutrients through the xylem to those lower leaves, but since there's a limited amount that it can move through these passageways, that means the upper bud sites get less water and nutrients. Once the plant is done with its vegetative growth and has reached its final height after the stretch, the lower branches no longer need any nutrients because they're not growing anym…

Can somebody please help me figure out what's wrong with this plant, at some point I did cause some nutrient burn but that's fixed now, but I can not figure out what is causing these white spots. It honestly looks like some kind of pest rather than a nutrient issue to me, but I cannot see any insects on the plant. This is my first time growing so I'm a bit lost at the moment.

there are 3 possibilities

  1. When you water droplets of water get on the leaf and the water magnifies your ligh burning spots in the leaf.

2. Some sort of mite it doesnt look like spider mite infestation but i would check under the leaves with a magnifying lens to see if you see the webs or tiny spider looking things.

3. Thrips which in my opinion is the most likely, The way the eat the plant is they rub thier face on the leaf until they get to the sap. Thrips arent ussually a huge issue for cannabis production.

Make sure you dont have spider mites ,
if you do have spider mites spray water on the folliage of your plants daily and maybe put on neem oil if its not flowering yet.

Leaf miners.
They're a real bitch to deal with since most safe pesticides don't kill them.
All I really do is spray the plants down with insecticidal soap or Neem Oil and cut off the effected leaves. If the plant is still in veg, it should be fine after a bit of recovery time. Wash the leaves the next day and try to get rid as much of that honeydew as you possibly can. Do this once a week or more and you should see improvement fairly quickly.
I also crush the effected areas between my fingers, which can damage the leaves but since the little fucks already destroying the leaf, it's not that much of a problem. Just killing the miners by crushing them can slow the spread of an infection.
Just make sure you remove the worst effected leaves. It's better to wait a few more weeks than lose an entire plant to a pest that won't go away.
Spinosad apparently works against them, but I've never seen it sold at any retail shops.

yup, looks like spider mites. Leaf miners leave damage that looks different but this is pretty typical of spider mites. They look like tiny black dots and leave behind little white spots like that at first. Take the plant outside and remove anything heavily affected, then spray it down real good with a powerful enough jet of water that it will knock them off, then spray on some sort of repellent or killer designed for them. They like to hang out on the undersides of leaves so make sure to spray that real good. The eggs are harder to kill so make sure to keep using the insecticide regularly even after it seems like they're all gone so you kill anything that hatches.

I've noticed that everything I grow smells of licorice. The buds themselves smell of the strain they'e supposed to and the licorice is undetectable until ground up, but when I grind it up and sniff it up close, I get the same licorice smell regardless of strain, is there any reason for this?

I've always used the same soil and nutrients, I have some triple cheese that smells obscenely like cheese but ground up and sniffed up close it has the same licorice smell. I'm not complaining, just wondering why this is.

NYC diesel related (also had this smell once ground)

its your nutrients temperature light combo.

Cannabanoids are mode through the isopranoid pathway which is very voltile becuase the compounds serve to go into air and attract predators to eat aphids and cool the plant down. These compounds are intentionally unstable and will change vastly with how plants are grown.

Change up your nutes and temps if you want different smells. I have found any weed i grow outside in Minnesota Smells like fucking lemons especially by fort snelling state park

Defoliate only the leaves that are turning yellow or have diseased spots. If you are familiar with source and sink in plants the leaves are the source and the bud is the sink. The leaves make sugars that the plants will use to produce buds.

Removing foliage can help with mold issues but generally reduces yield. With your grow i would suggest trimming all your side branches off early on leaving only the top cola(s) that will use the vertical space well and give you top value product. No one want a bunch of tiny nugs.

Cheap red and blue sets from China work just fine. Even if some lights are more efficient and save you money that way, there's no way it's going to be enough to recoup the difference between a $50 set and a $500 set.

These Mars Hydro sets have been around for a while and have a good reputation:
