    Default Gnats or manganese deficiency?

    I am not sure what is causing this. She is in her flowering stage now and something is eating the leaves. Can someone help me confirm?

    Kind regards, Victa

    Hi mate,

    It's not fungus gnats. They don't eat anything.

    It could be where some water has hit the leaves, then the lights burn into the leaves, but certainly not gnats.

    Hey dude, I haven't been feeding them any nutes, just plain water.

    I think it could be an air flow problem. I have an outtake fan but haven't got any fans set up inside the grow area yet. I'm guessing the plants are thinking they need more water as it's quite humid, which could be likely causing nitrogen toxicity. Would you agree? I'm no expert, so feel free to correct me if I'm wrong.

    Kind regards, Victa
