Plants are still growing good but not sure what’s going on here. It appears to be a magnesium deficiency but what’s causing it? Could it be a lockout? Growing in coco with 5.8 ph feeding at 1.1 ec.

OK so try varying your pH between 5.8 and 6.2.
Thats just general advice.
Next google the ratio for Epsom salt (magnesium sulphate) foliar spray and give it a dose for a few days and see if it improves.
There's a chance it could be slow light burn too so keep that in mind.
Make sure your ph tester is correctly calibrated as well.

Looking better. Did you bump up the feeding or add Epsom?

I’m feeding 1.1ec and I bumped up the ph to 6.0 today and gave its first foliage spray with calmag because I could not find epsom salt at my hydro store. I’m getting yellow tips now though which could indicate potassium issue.

Any drug store has Epsom. The grocery stores probably do too. Just get one that's pure Epsom. With no scents or crap added.
They're looking better though, so what you're doing is working too.

I would aim for 5.8 pH in Coco especially in VEG. I will let pH go to 6.0 in bloom no problem. What nutrients are you feeding? 1.1 EC would be low for some lines.

I’m using house and garden full line. I raised the ph because I tried giving them 5.8ph and it wasn’t getting better and from what I was told magnesium uptakes better with a 6.0ph
