Serious case of clawing caused by?

[Overgrowtho]

Anyone have an idea what is going on there with the excess clawing on the one plant (and a bit on the others)? I dont think its wind but Nitrogen. I havent been watering with much runoff so perhaps the salts built up to excess N?

I just changed my reservoir water and flushed at 650 PPM since Im in the mid-late veg.

I am using mostly a peat based media with chemical nutes 20-10-20 Dr. Bugbee formula.

those look like they got way overwatered at some point but at close up the curled leaves look crispy......you pH your water?

They are in soiless tho. I didnt think they were overwatered because they didnt have much runoff. It could cause this???

You should feed until runoff, just don't let them sit in it!

You should always water to substantial run off..........especially in a soilless medium.

Okay dudes I will flush the built up salts more and up my watering game so as to get better runoff each watering
