I was using only biobizz grow and had a huge phosphorus def. Was using RODI water and almost killed my plant. It was a momma so switched to an all purpose, concentrated fertilizer and problem solved.
I think I am running into the same problem using the complete BioBizz line; Alg-a-Mic, Grow, Bloom, and TopMax. Using all those at the levels recommended by the company, I believe I am still running low Phosphorus. I'm thinking of supplementing weekly the same all purpose fertilizer that I am using for the mommas, Miracle Grow Tomato Food at half strength (~600 ppm). Any comments?
