Can anyone help with diagnosis?

I gave checked ph and it's about 6.2. I've checked under the leaves carefully and np mites. I don't water the plants at all from the top. This is a DWC 5 gallon hydroponics system. Thanks for any help!

Seems a bit like a LED burn to me. How far is the light from the plants?

About one foot. I raised them to about 2 feet now.

Good rule of thumb says around 15-18" for a 1000w light .. but then again it can be diverse. Those magnified leds can be very intense with UV

Heat/light stress and ph is to high. Try for about 5.8.

What led is it?

The leaf curling looks like light/heat stress as aqua man said but im curious what your water source is? Do you add and magnesium supplements?

I use Cal- Mag - about 5 ml/gallon with brita filtered water that I let sit overnight before I use. I also use hudroguard....i thought it might be a calcium deficiency but adding alittle extra calMag did not really help....
