Do I need to add more cal-mag? What are the spots on the leaves?

Hello, Your plants look droopy which is a sign of overwatering also the brown spots on the leaves seem to me that it could be a pH issue. Double check your pH pen and always have it calibrated. How much Calmag are you feeding it now and how often? If it’s low up it an ML or two, see how she reacts. Cheers! 🌱

I have only gave Cal-Mag once and at 1/4 strength to the Bruce banner plants. The Massassin with the tiny spots all over the leaf hasn’t had any Cal-Mag yet.

Brown spots are signs of calcium deficiency. What is your ph/ EC coming out? If you are already adding calcium magnesium you might be having a lockout of nutrients. Personally I’ll flush my plants to 200-300 ec then give them a feeding right after I flush and let dry for a few day then then continue with there regular feeding schedule. Hope that helps
