I have 3 plants and one is starting to turn brown with leaves curling up
I have the same problem. Although it’s happening to all my plants. The tips turn brown then curl up.
h e l p!!
Sounds like nute burn or maybe pH.

Hope these help,
well I did a soil flush and added fresh nutrients
My PH level is 8 so I put some soil acidifier in to lower it. I am told this is safer than aluminum sulfate
The one that is struggling was a much smaller seed than the others.
But it looks like it may survive, Its starting to grow second leaves and the color looks much better
