how close is your light? is that 900w actual draw? LEDs are very focused even though it doesn't generate a lot of heat it's still very powerful and seedlings don't need a lot of light. Mine didn't really start growing until I maxed out the distance to about 52 inches, it's a "1200w" 250 actual watts, the manual suggests 4.5 - 6foot distance. maybe raise the lights or put a shade cloth.

It was the ph. I dropped it to 5.5. Plants started to take off but i stalled then for almost 2 weeks not sure if its even worth finishing them now

you ph'd your coco ? i dunno if you do, i never grown in coco.

like soil you need to test the water coming outta the bottom to get the right ph balance.

Put them into solo cups when they first go into dirt. You are wasting weeks waiting for the plant to grow roots out to the inside of the pot. Plants need to support themselves by building a rootball. By using huge pots right off the bat the plant will spend a lot of extra time growing more roots than necessary.

Good luck, BigSteve.

These aee autos so i was advised against transplanting. Maybe starting in rockwool cube rather then right into the medium ?
