Interesting.

I too have similar issues under a 630w cmh ...

My theory was that all the N issues can be tracked back to the buckwheat hulls.

I don't have enough drainage now in my soil and have to be VERY conservative with watering and the yellowing has not completely stopped either.

I think next round I will mix perlite into the soil mix for better aeration and add lots of bloodmeal and EWC to the mix again. Hope that will fix it.

But I do note that under the 315w cmh (blue spectrum bulb) the issues look a lot less pronounced.
