Help! my Babies are sick

[Iamroach]

I started 10 AK48 seedlings and have hit week three. After a bent stem scare I gave them a drop of superthrive for shock and now they have brown spots on some of the leaves and seem dry and crispy.
I have since replaced the rez with fresh water, a touch of SM90 and put domes over them to up the humidity with the 200w LED light 3 feet away.

Any suggestions for a new gardener?

take the domes off seedlings dont need high humidity.

sounds like nute burn.

what medium are you growing in. you need to give as much details as possible for people to diagnose your problem. pictures are great to

Anytime you can post pictures of what you have going on would be really helpful in helping to identify your problem. I hope these guys who posted before me answered your questions though.
