I noticed my 2nd one when it took off in bloom went cal mag deficient and really needed cal mag. Still overfed but my fault again. I'm thinking maybe just straight promix hp with lots more chunky perlite next time with just worm tea and very lite nutes later. Anyone else think Malawi takes more cal mag? or maybe just this pheno and looks christmas tree shape and very narrow leaves. I have heard of chelating oyster shell flour with vinegar, but what about gysum that is neutral ph? Reason is I think for organic, maybe some extra chelated gypsum or other??? right before and throughout flower as I use RO water. Peace... SR
