Sarge no worries mine all feed that way! It's the change from an all dry to a wet root feeding makes them well not happy for a few.

I start root feeding  when they are small so they don't have a drastic change to make when they get put on the autopot feed system

Autopots flood the tray as the plant feeds so it looks like they are sitting in an inch of water all the time. A look more often will show that it drains pretty well between floods, but those  roots are acting like they wood in a water culture, wet all the time in the lower inch or so of the pot acts and act an  awful lot like Deepwater culture, sort of.

So no worries drain it or let it drink it either way those girls will be fine. Just upset their feeding was changed is all, having to grow different roots to acount for being really wet can be a such a hassle.
