I'm growing 4 mj plants in my closet. Three of the plants look good, but one is getting yellow/brown spots on the ends of the leaves. it's alot more skinny/lanky than the others too. I am using 2 CFs, one 18 inch florescent (all about a foot away) and wal mart soil. They are all about 3 weeks old. wtf is happening??
how do you have the lighting set up? maybe its not getting enough light? do u fertilize it at all? Anything different done with that plant than the others?? Sounds like a PH problem.
You must be doing something different to that plant that youre not doing to the others Different soil?water?fert? and maybe its something to do with its position in the grow box, Send a pic if u can of the set-up, CWL
