I didn't even think about you using a one part feed. I don't know how you'd do it with that product.

Recently, I'm using a 3-part from Humboldt Nutrients but I'm still evaluating them. I have used Advanced Nutrients in the past and really liked them. Everyone says they are overpriced. I don't know the PureBlend line. Have you been to their website to see if they make a 3 part or a complementary product to what you are using with bloom nutes only? If you like the brand, I'd try that.

Fox Farms is supposed to be the bomb. Just be really careful with the FF Ocean Forest soil. Lots of folks burn their plants with it.
