I would advise using the 3-2-1 nute recipe; Only if you have plenty of room. Itried it, but no longer use 3-2-1, because it ate up all my extra space with useless lower foliage, and abnormal height. Actually, For those of you growing outside, I strongly recommend 3-2-1.

In side 1-1-1 is better, Imho, and for flower with height restriction's, i am becoming sold on the lucas formula, but I modified it, just a bit.

Instead of 0-5-10veg and 0-8-16flower, I add 1ml grow per gallon...so, 1-5-10veg and 1-8-15flower. This is just my crazy Chit'though. Goodluck lw
