Calcium Deficiency Part 2 better picture
CannaMom2started grow question a year ago
Calcium Deficiency right? Noticing on top leaves. I have been using CalMag every water but I did lower the dose for a few days in wk 7 Purple Lemonade as I was told I was using too much for flower. Also raised to 6.0 pH from 5.8 today.
