I made the suggested changes a few days ago, and for the last several days, not only has the calcium deficiency stopped appearing on new growth, but the growth rate has exploded - it's now growing at around 2 inches a day. Thanks everyone for the help! In case anyone runs into this problem...

Thanks for all the advice! Trying to piece together what everyone is saying, here's what I'm going to try: I'm first going to run florakleen through the reservoir for a few hours (as per the directions on the bottle) in case there was nute lockout caused by too much cal/mag. The new nute...

Aren't epsom salts for magnesium deficiency, not calcium deficiency?

It's consistently showing up on new growth. I've been treating the problem with CALiMAGic for about 4 weeks now (started at the recommended dose on the bottle and been going upward from there), with new sets of leave appearing every few days, and still each new set of leaves has this brown...
