I second this. With such a tiny plant in such a big pot the dangers of over-fertilization are much more imminent & severe as the begin of a NPK deficiency.Not going to be light burn down there but possible toxic salts buildup tho it's a little early for that. You shouldn't be adding any nutes yet with the rich soil you have in there. How big are those bags? Even if only a gallon there's still lots of food in that soil. Any particular reason to not fill them up? Would help air movement if they were near flush to the top of the bags. Really early for Bloom food.
PS: When you water you should be soaking the pot real good then letting it dry down until it feels light. It can be dry 3" down but still soaking wet in the bottom half.
Thanks for the reply. They're 3 gallon pots. The reason that the soil level is so low is that I ran out of soil. I got some more OF; I'm just trying to figure out how to repot it without disturbing the plant too much.Quite possibly some fungus going on causing that. Very poor air circulation around the base of those plants so I'd remove all the damaged leaves and maybe a few more lower ones to open up the bottom a bunch.

If you take the bad leaves off and make sure the fan is blowing some air around the base of the plants you shouldn't need to use any fungicides and the problem should go away. If the plants didn't like the OF you'd be seeing nute burn on upper leaves so flushing is not the answer either. Some runoff wouldn't hurt tho.Thanks for the reply. They're 3 gallon pots.

I also thought that it could be fungus. I'm going to order some Southern Ag's Biological Friendly Fungicide. It appears to be completely safe to use, so it can't hurt. And I should have some fungicide on hand anyway. BTW, has anyone here used this stuff?
Despite the name, FF says to use BB during the entire lifecycle. It's pretty mild, so I don't think it's hurting anything. I don't think anything I'm feeding contains salts.
One of my hypotheses is that the roots just hit the OF, and the plant doesn't like it.
And I water exactly as you suggest. I'm going to flush it with spring water, probably tonight.
