Seedling Stage issues

Hey everybody, this is my first time posting on here, and my second grow so far. I'm having some issues with some of my plants in their seedling stage and I'm having a hard time finding much info about plants in this stage of growth. 2 out of 6 look great imo, 1 looks ok, but 3 are clawing and seeming a little stunted. They are all being treated identically. It is day 11.

78°-83° F, 53% RH, 312 PPFD at the canopy level, germinated and growing in Royal Gold King's Mix in solo cups, watering with PH 6, watered with Botanicare Cal-Mag plus on day 6 at a rate of 2 ml per gal.

Any help would be greatly appreciated.

What is the inflow ec/ppm? What is the ec/ppm of outflow?

It's pretty warm and dry you might want to add another fertigation event or increase the amount of solution applied. When it gets warm and dry the media will dry out faster, which in turn, will increase the ec of the root zone. Was the coco buffered? Did you check ec of the coco before planting?

There could be a few things that are causing the droopy claw look but it looks like slight nitrogen toxicity.

You only started feeding on day 6?
