I've been giving them nutes the whole time, about 25%. I don't want to cut them all do I?

Here are a few pics.

The first one has a brown spot on the leaf, that showed up in the last 10 or 12 hours.

The biggest one's (last pic) leaves are twisting, this also just started in the last 10-12 hours.

All pics are of different plants...

Anything to this?

BTW...I really appreciate everyone's help!!! Thank you so much.
