how much is enough nutes??

is there a nute chart i should go by per week for my white widow,3 weeks from seed,dont want 2 burn them.i've got a tds meter 2 regulate nutes.

Just ease into feed half what the nutes say to feed and ease into full strength.There are plenty of ww posts on the best way to feed.My understanding is that they love to feed so you should have no issues.

I dont feed my plants any nutes until right around the 3-3 1/2 week mark. Nothing but water and clonex solution up until this point. I use house and garden nutes aqua flakes for hydro, it is very reasonable price wise and comes in a easy to use A and B 2 part formula. If you go to the house and garden website, you can use their nutrient calculater. Fill in the blanks regarding what kind of grow you are doing, and it will give you a custom nutrient schedule from week 1, all the way through flowering. Awesome site, great nutrients (on behalf of my experience), easy to follow feed schedule and awesome prices. good luck with that
