More gypsum (aka calcium) for potted tomatoes?
Really getting into tomatoes, and it appears that calcium is particularly important to tomatoes based on the research that I've done so far.
Given this, would it be advisable to up the gypsum in the 5-1-1 mix? Maybe double it, or 1.5x? Or just keep it the same?
Obviously too late for this year, but I am getting hit with some BER so I'm just wondering if this might make a difference for next season.
