Serious case of clawing caused by?

Overgrowtho

Well-Known Member
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???
