There showing signs of too much water. Are you aerating the water? How do the plants receive water? Is the water reaching the net pots, or do you have an air gap between the two? Can you send pics of underneath?

Thank you for repling,

The aeration was down for a day, but the curling was happening before that. The net pot is reaching the water and there is a slight gap between the water and lid.

Here are the best pictures I could get of the bottom.

Thanks again,

Your plants are waterlogged. I think I've got a fix for you.

There needs to be a gap of air 1/2"-1" between the bottom of the net cup and the top of the water. The bubbles will pop and give your plants a great water to air ratio. The roots look long enough to grow in the water, so I would probably go with at least a 1" gap. Let the gap increase to 2-3 inches before adding fresh water. Should notice a big difference within a day or two.

-On a side note, your roots look a little brown. That could mean you nutrient level is a little high. Do you have a meter to tell the PH and nutrient strength? If so, post them so we can take a look at it.

Thanks, I lowered the water level, we'll see what happens.

I do not have a meter, but the last time I added nutrients I noticed the roots had brown on them, but whitened up after a couple days. {{gwi:1001114}}From Hydro Experiment *Peppers*

Is this low enough?

Not if the water is touching the net pot. I know this sounds like it will dry out your plants, but trust me it won't. The bubbles popping up on the net pot will keep it plenty moist. Leave at least 1" of air, between the top of the water and the net pots.

Alright, sounds weird but I'll trust you... It's been lowered to 1" below the bottom of the net.

I'll keep you updated, you can also look at the album my pictures are from.

Thanks again for your help,

Jeff

I agree with urban. Your roots can't decide how to grow. Air roots where the splashing water hits them or water roots where they are completly submerged

I concur. Lower the H2O level & you should be golden : ) The roots have reached the water so there is no need to worry about the net cup not touching the water. I will say you have a great looking plant! Hopefully this will help and your plant will look bold once again
