Help please!

Hi i have 3 seeds (canuck auto chees, oasis crystal widow auto, oasis auto chem og) that i germinated in water until the seed crack then it was planted (7/12) into a cheap generic seed starter mix within 2 days all had sprouted. The bag does not indicate that any nutrients are added to , or available from the soil. It drains well but I'm not sure it holds much water. The light I am using is a full spectrum led I had from an old planted aquarium at about 10 or 12 inches above the seedlings. i have encountered a few problems so far. One of the seedling failed to completely lose its shell, outermost part came off but a membrane remained that didnt allow the leaves to spread. The issue I'm most concerned about though is one of the nicer seedling decided it was gonna start yellowing. Im not sure if its nute deficincy, over watering, or what. Thats where i am hoping you guys can come in with some opinions. YES I HAVE READ PREVIOUS THREADS. I water when soil is dry and containers feel weightless. attached are photos.

Very similar to Promix HP, cept pretty chunky

No nutes in it, so they will need something in a week ish or sooner

What's yer water pH at, says it has buffers , but using ,8+ pH can be too much

Autos are supposed to not do well on transplants
I would move them to their final pot soon
And yes use better soil that stuff just washes right thru

@BobThe420Builder my tap waters usually arond 7.3 ish. I use water from a well and not municipal water, might not be to important but i no my water doesnt have the added chlorine and other chemicals the pump into the municipal supply. I have the technaflora recipe for success nutrient bundle. Would it be alright to water with a diluted dose of their thrive alive b-1 red? It says 1-1-1 and is a seaweed based product thats supposed to aid in root development and what not.

@Herb & Suds I have read about transplant issues thats why i started in cardboard tubes so they can be planted directly into my 7 gallon fabric pots i have ready and waiting outside. The soil is better homes and gardens organic potting mix with all nutrient levels in it being under 1%

No clue on those nutes, but yes, they will need food pretty soon

Hi just wanted to update, I awoke this morning to find that my crystal widow seedling did not make it. It was shriveled right up. I checked the roots on it, it was about a 3 inch long taproot. I just started germenating another seed this morning hopefully i have better luck with this one. The other to 2 seem to be doing fine. Any suggestion on how long lights should be on? And when would be the ideal time to put them outdoors into their final pots?
