Seedlings problems?

Screw it. When in doubt, attack. A tv character taught me that once.

1L repotted. 1.5dl water. EC 0.1 going in, 2.2 going out. Higher than it should be but it's the only soil I got. PH 6 ish. Big lights on, 18/6. Pray.

17 hours later and they are not dead. Seem to be doing alright in fact. The Blueberry still seems stunted, but the others have put on more growth than the last few days for sure. Thanks for the advice.
