White roots, or nute stained, is what you want. Brown and slimy is no bueno.
Right, and I have been constantly checking roots. I’ve had some issues at the start of the plants life with mold on the rocks (water/light, it happens) so added H2O2 and it cleared it right up, but have used enzymes religiously since.

It most likely was algae if it was light/water related. I use bleach for sterilization. A couple ml per gallon.

I’ll check the base. How much water is too much water? I usually kept it level about half way on the pot, I would think 3.5 or 4 gallons.
As long as it is lower than the bottom of the pot it should be fine. You want an air gap between the net pot and water. About an inch.

Is there a good rule of thumb about water levels throughout the plants life?
Need water level hi in the seedling stage so the water gets all the way to top.

After roots drop just need to keep an air gap about 1 inch. Other than that no rules really.

Just to be clear, The 1” below the net pot you wrote earlier?
Yes. After the roots come out the bottom of the net pot. You lower the water level so there is a gap about 1 inch. You want the top of the pebbles to be dry. The base of the plant should never get wet after the roots drop.
