when you switch to 12/12 you should still feed them with veg nutes for 1-2 weeks... or better yet, week 1 ---50-/50 of veg/bloom nutes.... week 2 ---- 75 bloom/25 veg.... week 3 -- 100% bloom...


first week to 2 weeks of flowering the plants stretch, so of course you would need some nitrgen to supplement or it turns yellow leaves to soom....

I was told this from a great grower....
