I have a few outdoor plants, one of my plants "Green Crack" was looking good lastnight, today when I got home alot of the leafs are DARK brown and look all fucked up. Any tips? I don't have a good camera at the moment..
It's hard to say without pictures, but really dark brown sounds like fertilizer burn. Are these outside plants in the ground or in pots? Did you put down fertilizer in the ground when you planted it, or in the pots? Time-release fertilizer pellets or just too much of any fertilizer could have been too 'hot' for the plant. Also, was there a chance it got really hot where it was for a long time or that the plant didn't have enough water?
