Seedlings stuck? (Pic)

I'm very self critical and really appreciate your encouragement I'm kinda disappointed in the whole Hydro scheme of things I think I'd had a much easier experience in soil (insert laughing emoji) when I was watering by hand it was ALL organic I'm a huge huge fan of organic and learning the soil wide web I'm no expert but ive spent hours listening to Dr Elaine Ingram and build a soil etc I have a ARENAL of down to earth nutes humic acid, worm castings, sea bird guano for flowering. Bat guano 7 5 3 ratio vegan blend 3 3 3 kelp meal pretty sure theres more but yea i wanna go at em organicly so my autos they get their first run in soil, I'm using fox farms 3:1 ratio happy frog to ocean blend ive added 2 perlite AND vermiculite some pots just have Gia greens 4-4-4 and some have the 4 4 4 and bloom marked accordingly I was a little nervous just throw in both all steamy and hot like canuck and being a rookie figure I'd rather brew a tea and foliar and or top dress and gain some experience.... this coco and watering 6x a day getting ppm right to bot burn bc feeding so often finding a quality ph pen, just bought a blue lab for 90 bucks and I love the 40 dollar res tan constant monitor I have I finally feel I can trust my ph those cheap Pens are JANK in my rook experience and I've got 3 different ones.

Also ordered 2 ac infinity 69 pro controllers as I already have 3 of their exhaust fans on 2 4x4x7(or8?) tents and 4 of their rotating fans and 2 good dehumidifiers as I prepare to dial in VPD and hopefully flower these things someday

Also I'm experimenting with natures own living soil for auto flowers, a question I have is does the 2 3rds of potting soil need to be plain soil or will using worm castings and happy frog make it too hot right now I just put happy frog perlite vermiculite living soil combo and autos have got dosed since first watering with great white in the water

Ac infinity is teasing us with a 9 inch pole clip oscillating fan says it isn't available yet like same don't show it then lol

So I've left them alone as suggested and shesh today's giving a little splash of aqua one of the 2 seed shells FINALLY fell off I'm guessing I probably stunted both of them didn't I

Remember, when they're young and don't appear to be progressing...lots of the action is happening where you can't see it. In the soil.

I hit them with a pinch of great white in the RO water after seeing almost instant results with it on my cuttings in a cup of water yesterday, for the first time ever I have not just 1 but about 7+ clones pooping out some white strings
