I have 2 Mi5 that are 12 weeks old. They are yellowing out fast as autos do at the ends of there life cycle. The problem is the buds are far from finished. They are still yet to fill out and all the pistols are still white. It seems like they still have 3 to 4 weeks left but the leaves are fading fast. Plus in 3 weeks that would be 15 weeks for a strain that rarely takes more then 11-12 weeks. Anybody got some advice or explanation for what's going on and what I should do?
