Do you need nitrogen when flowering?

I have bud blood as my flowering nute (0-39-24) and I've heard you should have little or no nitrogen during flowering? Is this true? Otherwise I'm going to have to find some nutes with a little N :/

You need a lil' bit of nitrogen during the flowering stage, or else your plant will turn real yellow from the stretch.. and the leaves will fall off prematurely..

I'am going to reccomend these ferts>> http://www.jacksclassic.com/dynamic_duo.html

IMHO, this fert is the best for soil.

Im growing 4 soil plants in air pots with this fertilizer.. and there bigger than my hydro plants.

$20 bucks and your set for a good long time.

Best of luck, CG
