It's not a nute issue... I think you may have a bug of some kind but I'm not sure. Have you looked underneath the leaves?

Difficulty identifying leaf problem - maybe it's insects?
I'm having trouble figuring out what's going on with my plant. The cotyledons and lower fan leaves are getting irregular shiny patches varying in size underneath, with yellow spots directly above them on the top side. It's really hard to photograph the shiny patches. Thrips?

White Spots on top of Leaves
I have discovered white spots on my plants. I think it is white mildew. From what I have read, the spores cannot be killed. You can only stop them a with pesticides or, if you are lucky, with a milk/water mixture, but you cannot remove them completely. What should i do?

When using a Apple cider vinegar/water mixture is it ok to spray the entire plant, leaves bud and all to combat Powdery Mildew (PM)? I’m assuming it’s ok and may help prevent the PM from infecting the buds leading to bud rot?

Pollen sacks or powdery mildew?
I noticed what I thought was powdery mildew on a leaf, then noticed funny looking things right next to the powder. I think these are pollen sacks, and if they are I want to know if anything is recoverable, or if I need to scrap the whole plant/grow. "Second Grow" on my profile

Small white spots on leaves in germination phase.
Does anybody know if those small white spots are ok? I have water 7 pH and I add some citric acid to lower it to 6 pH, when I sprinkle the soil I lightly sprinkle the leaves as well and I'm not sure if it's the effect of dry citric acid or something else. Thanks.
