What's this leaf trying to tell me?

I was doing some light pruning on this 100 day auto flower (all gas og) around day 60, as I hadn't done any yet this being my first grow I'm learning the plant. My leaves had been perfect all the way thru, new leaves look fine, but some leaves that came in a couple weeks ago are looking like this one.

I'm feeding EH bloom A/B formula, 6ml/GAL, calmag 6ml/GAL, 10 Gallons in res, replaced every 7 days, topped up with same formula with 1-2 gallons every day or two, PH maintained 5.8-6.2

Same leaf pictured, few shots to get a good look at it. Others mostly fine, some with same look.

Its saying i need calcium.

Phosphorus deficiency. Not calcium deficiency.

Looks a lot more like Ca than P to me. Maybe a little nute burn going on as well or just that. It's not critical so don't throw a bunch of stuff at it and maybe make it worse. Little less feed and a small amount of calmag is what I'd do.

Thanks for the interpretation. I appreciate it.

I recently ran out of Calimagic, and switched over to Greenway Biotech (GWB) calmag (cheaper). I was feeding 6ml/gal Calimagic, now doing 10ml/gal GWB calmag. My RO water starts at 30ppm, so there's nothing else in the water.

I also moved the plant lower to the ground, as I couldn't raise the light any higher - s33 ionboard at roughly 18" now, 6' tent, 27 gallon tote. It had stretched to about 12" on me. Had the tub raised a bit to make gravity draining easier. Now I just use a pump to empty.

Not worsening I think, so gonna stay the course, but harder for me to tell now vs when this showed up. All my perfectly flawless leaves, was easy to see when some started becoming not perfect.

Gonna hang onto that graphic, thanks for that.
