Is this calmag deficiency?

Growing in coir using GH trio. 340 watts of led in about 4x2 with filtered water

this is my third batch of plants but my first deficiency. I kept having problems with overfed plants my first couple rounds so this time I dropped the ppm low, cut calmag out, and went right to mid bloom mix when I flipped instead of working up the chart like before.

This is the first time my plants arent super dark and also my first deficiency so I finally found the bottom and my next round should be dialed in.


I’m pretty sure this is cal/mag deficiency since I went from tap to filtered, didn’t use calmag and running led.

Flipped about five weeks ago. The leaves looked a little off for like a week and then suddenly got much worse over two days.

burnt tips I think are from letting it dry out a couple times in veg. On the very right you can see how dark the leaves are on an older plant of the same strain that’s at 11 weeks.

might be pH as you have curling tips. I'd check pH, record it, give some calmag, check pH again, it if all looks good leave it alone for a while and see happens. try to give more info when asking for help. can't help you well if you don't.

There's no such thing as CalMag deficiency. But that does look like Ca deficiency. Make sure your pH is good too.
