So this is my GSC At Day 12

She is in 5gallon bubblebucket DWC, about 2.5 gallons of water in there with 10in net pots. PH is 5.8, and has been that way and steady for most of the grow (ph fluctuated the first few days after transplant). I added advanced nutrients 3part MGB about 4-5 days ago, but only at a very low dose of 1/4 recommended for seedlings. None of the other plants are showing signs of this, but they are different strains.

My big questions is; is it a deficiency or nute burn?

I was thinking she needs Cal/Mag from what my research has found me. I just wanted some of that :420: expert advice.

I have some Cal/Mag to render the problem if that is the case so just let me know asap.

PPM=250ish PH=5.8 Rez=69-71F AirTemp=75-82F ON 68-72 OFF
