It's basically all I've used for the past few years. If it wasn't a solid nutrient system, I'd I'd be using something else right now. You're using the Fox Farms Weekly Feeding Schedule from their website, right?

The only soluble I use is Cha Ching on occation. But I strongly recommend you be careful with the solubles, as they are better-suited to those with growing experience. Give yourself a few successful grows before messing with 'em.

About half way through flowering you can ease-up (about half) on the Big Bloom and start giving 1 tsp per gallon of unsulfered molasses, per week. (Grandma's or Brer Rabbit are common and available at most grocery stores)

This might get moved to one of the growing forums...
