Marijuana

Just completed week 1 of flowering.

So I had four different strains growing, and one of them had a bit of dust on its fan leaf. looked closer, oh shit its powdery mildew. I'd read about it, but never dealt with it until this grow. shit.

So i cut that leaf off, disposed of it, looked the plant over, and noticed two other dust spots on other fan leafs in different locations. shit. apparently that strain was just vulnerable to powdery mildew.

So I looked the other three plants over really closely, no visible signs of infection.

I didn't feel comfortable smoking the infected plant. And I didn't want it to infect the other plants. So i trash bagged the entire thing.

My airflow is high and i've got fans in room. But I am living in a region that has PM. Here's my questions:

I've got three more plants in the grow room that have no signs of infection. What do I do to make sure they stay that way?

Peroxide as a curative. Oddly enough, foliar feeds applied in a mist over the leaf surfaces.
Hit the tops and bottoms of the leaves the best you can. When it dries, the salt film left behind alter the leaf surface pH, making the area non-conducive to PM growth/infection. PM tends to stop infecting leaf tissue when the plant is passing through week 8 flower and leaves begin to change color, but it does then start infecting sugar leaves if you don't have it under control by the last flowering days.

i spray with vodka lemon juice mix, PM is a fungus and fungus don't like PH changes like that. the vodka and lemon i spray is the same stuff i drink so it all cool for sure. i try not to spray flowering ladies at all if possible though.

Wiping mildew off with a 1:1 mixture of water and milk is a very simple organic remedy supported by scientific literature. Paradoxically, mildew likes high humidity but can't grow on wet leaves.

Been reading up a lot on growing mushies since I realised it will be a lot cheaper to grow my self rather than keep on buying kits and risking having them seized.

I'm thinking I'm going to start right off to mono tubs but dunno what substraite to use.

I've read rye is ye best.
But I live in the U.K. And can't seem to buy big bags in any shops.
Same goes for popcorn
I've read bird seed is a good one but I've ha a look in a few garden stores and they all seem to be loaded with sunflour seeds what's supposed to be shit.

I've looked for manure but you can only use fresh right ?

Same goes for brown rice flour.No big bags any where and I think it was rather dear.

If it comes to it I'll order online but my long term thinking has me paranoid because I know someone who used to grow small amount of weed for years on end got caught and ended up getting jail instead of let off because they went back on his bank statements and seen he had been ordering bits of soil and fertilisers on line.

I have an Idea. Its kind of exotic though so don't freak out. Nuture it.
If you dont have space, like a living room or garden, plant it somewhere in the wild where you think it'll grow and come back in a decade

I don't know about seasol specifically, but if it's like kelp tea, it's pretty mild and more for promoting good soil microbes than a straight "plant food".
Their website didn't really list it's analysis or contents, beyond "seaweed extract", so I dunno.

got a combo seasol pack, 500ml 'health treatment' along with 500ml 'plant food'. Ive been using them about every second day. Also have some test-tomatoes going to test limits of watering along with other things.

Plants (autoflowers) have begun showing the hairs off the small growing bud sites. only one plant at this stage but none of them have had LST/supercropping or anything (and theyre small plants) so will only have one main bud cola. How long should I wait before swapping lights and lighting for flower?

they've had 23/1, with an hour cooldown for the lights. When I swap should I go to 12/12 or 18/6? or some people have said leave it at 23/1

I picked up some kira white thunder seeds yesterday. Is it possible to just stick them in a pot and grow them like a house plant?

Apologies if this seems like a stupid question, the only thing I grow on a regular basis is beetroot.

Lmk what YOU think! It is an indica dominant strain

Also I don't have a microscope to see trichs so that's out of the question. I'm always so indecisive on when to cut. I know it's not ready yet but I never know for sure when it really is

use a magnifying device to find out the color of her trichromes.

>Transparent -> not ready
>milky means -> okay to harvest
>some milky some amber -> perfect time to harvest, (at least I think that)

How many flushes do you get from a bag opposed to a jar?
Do you find the injection "port" better?
Did you buy the bags pre-sterilised or made yourself?

Let me know big man, might try next time. Although I have no idea what the fuck to do with that many shrooms.

This is my third grow (over the course of a decade), and the best looking so far (the first two didn't have a vent fan set up and were huge messes). Mixed up the seedlings early on so I'm not 100% sure what the strain is, but given the characteristics and what I started with, I'm pretty sure its either Auto OG Kush or Auto Blue Cush Fast.

Temps are around 28c, which is a little higher than I'd like, but much better than I've managed before.

I think the fan leaves are getting light damage (probably because I'm still running 18/8, because Autos) but I don't think it'll get bad enough by the time I harvest. I don't have a very steady hand with the scope, but it looks like about half the trichomes are an opaque white. Given the rate its been maturing, I went ahead and began the flush.

I have to have a smoke alarm check in the building I have a 2 plants in, they don't need access to the room the tents are in, but they want to kill the mains power to check the alarms, which is obviously bad.

One plant is about a 5 weeks old, still in veg, the other is in week 4 of flower. I expect the power to be off for a maximum of 15-20 minutes. Will this be that much of an issue? It will throw my timers off which is annoying, but will something like this be enough to stop the plant from detecting dark for the short period the power will be off? https://www.lights4fun.co.uk/i/q/LL141705/3-warm-white-zap-led-battery-push-lights

It doesn't say how powerful the lights are but they're only for stopping complete darkness, and battery operated being the main thing.

Bumping this because I now have a new problem. My ceiling is leaking and will most likely result in the power being cut to repair it.

What is the absolute cheapest form of battery powered lights needed to keep a plant alive?

Yeah, interrupting the light period with darkness is fine up to a day or so. Its the interrupting the dark period with light (especially when flowering) that'll fuck things up for you.

Sterilize your substrate on your own, it's easy and you can exclude one fuck-up factor out of your equation. That leaves you with the spores, try different vendors and maybe try to get both, syringes and spore prints. You just need one successful run to keep this going for as long as you want to

I tried two seperate vendors for both spores and substrate. Althought I got the spores off ebay so thats probably why they weren't up to standard. Its very hard to find decent vendors here even online.
