Currently growing an ebb and flow setup and am using bc bloom and grow I have noticed recently in the directions it recommends adding boost also. Are you holding plants back by not using the boost?
the nutrient mix or mixes you should use are closely related to the growth stage of the plants. Seedlings Veg Flowering Pre-Harvest You can damage little seedlings by using a heavy mix or you can even burn a grown lady if you make the mix very highly concentrated that pH goes above or below the sweet spot. Check and post the N-P-K %´s of the nutes you are using and the stage of growth. That can give an idea if you should or shouldnt add more nutes to the mix. Peace
