First Post Bottom of plants Dead? have pics

[using foxfarm big bloom 4 tablespoons per gall]

I got a feeling you need to reread that lable, thats almost double what I put into my girls feeding cycle.

Your plants are burnt, from nutrients, not light, nor lack of.

After looking at your pics, I'd clean all those yellowed leaves, all the dead hanging about, get rid of it. It only invites more problems.

I grow naked/verts also, but I put my plants on rollie carts to spin them, hell sometimes a couple times a day. But feeding 2oz's per gallon seems way high, I use PBP and use 1oz per gallon, and have to play with that with some strains, going down to 3/4's oz per gallon, then a 1/4 tsp of KaBloom in flower.

Also, running AC, you usually need to run a humidifier also as AC strips air of mositure. I prefer big tubs when tree growing, 30 gallon and up, nice layer of LavaRock in each. I didnt see drain pans under your tubs, you can do that, but I would poke holes down into my rootmass to get some areation and new nute pathways into the mass, the roots love being pricked up a bit.
Good luck!!

ok thanks guys
