Can anyone diagnose this?

They are ilgm gscx autos. About 6 weeks old. They get fed 3tbs of organic 4-4-4 and 3-9-4 per gallon of medium. I use tap water phed to 6.5 and last week or so ive been adding 5ml of calmag to the water. They are on 18/6 light cycle, avg temp 77° and 55% humidity. I have a slurry sitting currently and will check ppm and ph but was just wondering if this deficiency jumps out to anyone…

Looks like more than one…

Ferts used are described in original post as are pH levels of my watering.
Slurry test showed no change in neutral water after sitting 24 hrs. Will check ppm now…

I’d get away from tap water. I just don’t trust it. Since I moved to RO, spring or rainwater, I have had zero uptake problems. This looks like an uptake problem…

I live in fl and my tap is well water that i presumed to be a good source. Ill maybe try switching thanks. My tap runs about 60ppm and 8 pH on avg. Which i will adjust to 6.7 with GH pH down. And 5ml calmag

Keep up with the cal mag: Mg and C defs.

Well water is better than my tap water for sure. Also I don’t believe this to be a lighting issue because of the overall distribution of the damage.

The following is a really good video from a stellar channel:
