Small Nute Problem

I'm just doing a small stealth grow at the moment. There are four babies in this 5 gal. bucket i rigged and i'm flowering them from seed. So my question is, the only nutes i have is something called daves bloom booster its 10-20-10 ratio. But, should i have to worry that much about nutes for such a small grow? And if so, a regular dose or 1/2, or what? thnks in advance for any help.

don't use nutes with seeds.

Just Ph your plants, until there at least 6 inches high, then you can slowly introduce nutes to them.. gradually step it up, otherwise you will burn your plants. Remember too that PH is important.
