I tried going with almost no N or Ca in flower and it has worked but not as well as I was hoping. I think I could probably chop these at 6 full weeks of flower and enjoy the high, they are as sticky and smelly as I have grown  but I also think it cut the yield by about 1/2. Next time I will try dropping the N to 0 farther into flower and Cal/Mag I am still uncertain. 

I do recommend GIECO and if you mention CMP they wont have a damn clue on why you did
