These clones are on day 10 since i put them in solo cups. Growing in Promix HP with added perlite. Feeding them Floraflex nutrients for a total of 300 ppm(150ppm calmag + 40 ppm silica + 110 nutrients). Temps are 27c/60rh and the first feeding was 5.6 ph and the two following were 6.2 ph. On day 8 i did a foliar spray with Floraflex Veg Foliar and Grotek Gro-silic but i noticed these issues before that.

You may be blocking the Mag with too much calcium. They're tricky to balance sometimes. What's your tap water like? Or using RO?

Try epsom salt (magnesium sulfate) in a Foliar. If it’s Mag it’ll show improvement.
1/4 tsp/1L water for Foliar. No need to ph as you are only spraying leaves

Could be ph fluctuations. I’ve seen it happen before and that was the problem.
that or overwatering.

That looks like a calcium def to me. Once the plant gets to that point is will take a week or two to get it back on track. Typically they will not up take much in the way of water or nutrients for several days. I would keep an eye on the amount of moisture in the pot and not over water. Leaves will get dry be leathery and will end up dying off but the plant will be fine. Once you start to see new grow the plant is on it way to bouncing back.

Make sense.

should I be letting my coco dry back more?

if I’m at 1.6 now what do you suggest I drop to?
Could you be a bit more specific on your conclusions? I’m all ears.

im running co2 and high powered leds.

sucks knowing also that if my vpd and room was really dialed I probably wouldn’t be having this issue at all as 1.6 for these size plants doesn’t seem to far off? Video just now lights out
