tried big bloom awhile back. when i was trying hydro setups out. worked pretty good just didnt like dealing with the ppm's. and i ended up killing it. check your ph levels as well. Just use it sparingly. Check guides on hydro. Im not an expert. I moved to soil. easier to take care of. and smoke is a little better.
all I know is your not supposed to use it for a recirculating hydro setup. For soil I heard its great but I have not personally used it. I have smoked results from it though and was satisfied. My buddy uses their whole setup. BioBizz
Use the directions but feed first couple times at half strength and then go up to regular. He said that in flower you may end up trippling the flowering nutes but the plants eat it up.
BioBizz Bio-Grow can be used either by hand to manually water your potted plants or through a drip feeding run to waste irrigation system. Organic nutrients like Bio-Grow will not keep once mixed with water so you must use whatever nutrient solution you mix up inside of a day.
Bio-Grow N-P-K = 8.0-2.0-6.0
Bio-Grow is an organic liquid plant food that is to be used throughout the growth phase of the plant. Bio-Grow can also be used during flowering as a supplemental nutrient or plant tonic.
