I'm wondering if you have too many plants in a small space. They'll get much bigger than that. I'd consider flowering them now. Sacks of pollen will start to show on males. They won't produce bud. Transplant to 5 gallon buckets or bigger. At the end of their life, the leaves will yellow, but only then is it normal. Any time before that might indicate a problem. Go easy on the fert as miracle grow is some hot stuff.
polishpollack Reviewed by polishpollack on . My grow closet. I'm growing nine plants with two florescent lights. The brightness of them are 1570. The light appearance is warm at 2500k I use miracle grow soil and I use mircle grow fert. I give them 24 hours of light. I keep a nice size fan in the closet. I usually keep it on low but some times turn it up to add more wind in the plants. (I call it "exercising") this is my 1st grow but I have read lots of post and info about. I plan on upgrading and purchasing everything in due time. My plants are around Rating: 5
