Help Identify Deficiency

That mix is pretty good.
And a Calmag will do the trick. Don't want to overdose and get a toxicity. What brand did you use for interest sake?

I threw in some Botanicare Cal-Mag.

I took gnomes advice on the Cal-Mag at low dose, didn't think it would hurt. What do you suggest for Ca only?
Started them from clones. I had them on 18/6 under T5's. To get them ready for the sun I took them outside the night before and kept them out of direct sunlight the first 2 days.

I like BioLink 6% Ca, or Calcium 25.

You just explained why they're flowering already.
