Something is eating my beloved ones. The leaves are getting tiny black spots and discoloured/damaged areas. Pics in the comments. It is feminized WW 3 weeks of 12/12 lights. The disease seems to attack all leaves, could it be spider mite? I have read all the tutorials and didnt find definitive answer.
I ask for advice of more experienced growers, help

leaf miner, spider mites, or very small drug addicts. if you can get a sharper closeup and you have spider mites you might be able to photo graph them and solve your mystery.

Get some fossil dust and spread them in a circle around your plants when you start your growing season. If you're using a greenhouse spread it around the outside of the greenhouse instead. Buy ladybugs, 1500 for outdoors and 100 for greenhouses. A solution of water and soap spread on your plants leafs before you release ladybugs will kill off most any problem you have with insects.
If it's indoors use straight lemon juice or simply have a fan blow on it directly.

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.
