Generally speaking the Biobizz nutes seem inferior compared to the Plagron. The plants were just not responding at all. I have no pH issues, water when the medium is almost dry so no overwatering issues, still the plants looked like there were not being fed whatsoever. I switched back to Plagron Alga grow and bloom and could immediately tell the difference. I lost a bunch of fan leaves and probably a good week of growth but I hope the next few weeks make up for it.
