Hello Roll it up, nice to be back. I keep having trouble in my garden and I was hoping someone could confirm what I beleive to be a magnesium deficiency. I've had great luck with people helping on here before, so I trust I will again. I use pro-mix cc, my conditions are near perfect, co2 burner, RO water emerald harvest with photo synthesis plus, silica, and calmg. Nm if it is in fact magnesium, should I put Epsom salt with the calmg? Thank you all for your help.
