Do any of you Hydro gurus out there have a good calcium supplement recommendation for BER on a plant in a DWC system? Ive been using Flora Nova both Grow and Bloom and have not used any supplements and now my tomatoes get to about ping pong ball sized and then they get the dreaded black spot, I want to try and fix my toms and also prevent this from happening on my chiles.
