You know.. big bloom is for flowering, right? You were feeding bloom nutes during a 2 month veg. That is maybe one thing to consider. Also, MG is nuted. You should never feed more nutes unless you're using MG Organic Choice, which has nothing at all in it. Also, MG is not suited for MJ. Its nutrients are more suited for tomatoes or tulips. Since you're aleady there, though, flush the shit out of it. Tomorrow, flush the shit out of it. The next day, flush the shit out of it. Then, to me, the leaves are "blanched," like they need N. N is the first thing plants need.. not P and K, as in your Big Bloom feedings. See this:

Next time you try this (whether or not this one works) I suggest you get MG Organic Choice Potting Soil or FoxFarm Potting Soil and follow that schedule to a tee. Also, it would help to get seeds online, since you will be able to control the genetics yourself. Get seeds that are labeled as "easy to grow".
