If u absolutely want to use nutes. Fox farm is a tryed and true method. If u ebay it. U will pay around 40$ to 50$ for the fox farm trio pack. I use it on both my inside and outside grows with outstanding results for both. With feeding every other day with just water feeding inbetween using nutes.. my real advice. Use your nutes on one of your ladys and simply observe the changes between them. You be the judge.
