I have 6 clones vegging (3 White Grapes by Hazeman and 3 Kosher Kush by RP) under 400w mh, they are in 200mm pots (don't know the volume) containing a 70/30 mix of coco and perlite. I water them pretty much as needed, which tends to be once every 2 or 3 days.
They have only been under the 400w for a couple weeks, but the plants are pretty old. I took cuttings before flipping my last grow to flower, and so these cuttings were probably kept in solo cups for a good ten weeks after they rooted.
I am getting black and brown dried out spots on my leaves, and graying dried out leaf tips.
I can't see bugs for the life of me, I saw a few weird bugs on a single leaf about a week ago, they were like really small (a couple mm or so in length) worms/caterpillars which were completely translucent, I have a lot of experience with bugs and cannabis but I could not identify them.
I have since treated with several thorough sprays of insecticidal soap and some root drenches with azadirachtin and have not seen them since, yet the damage persists.
My suspicion is this is bug damage, that is exacerbated by quick onset to mould due to high humidity in my grow room (it is Autumn here and I don't have a dehumidifier).
I should point out, I don't think it is nutrients or Ph, these plants are clones from my last run and are getting the exact same nutrients, maybe not as heavy on the dose but the affected growth tends to be old growth rather than new, so as far as I am aware that rules out nutrient problems.
Any help would be greatly appreciated! This issue is also affecting my mothers and in particular I would HATE to lose my cut of Kosher, that shit is stanky dank and the yield is on point!
