Thanks for the feedback! She's a GTH1. I think you are right, but I haven't had a chance to see with my own eyes. I get back there in 4 days. All these plants are on the same res, how do you recommend giving her a little more mag than the others? Also, what rate? I do add cal/mag to my water to .3EC (from 0EC).
1-2ml per gallon calmag foliar spray should do the trick.
Spray a couple times a day. Spray water only every third day.
