So you find you need calmag when feeding with flora nova bloom? I haven't needed any so far, just curious how long you've been using it. I've recently switched over to the flora nova line and love it so far, I'm growin in hempy's btw. I've noticed my biggest purple cindy is a little more pale green under the hps, but when I pull a leaf off and take it out it looks fine, so cant tell if she's needing some calmag or not.. I wouldn't complain if she got a bit more green though. I would add some grow nutes, but she gets rams horns easily, so that's out.
Nice lookin plants, I like that little white clip on fan too.
