It is my first time growing with metal halide. any help would be greatly appreciated. dont want to loose them. I have four 2 sour diesel auto. and 2 blueberry autos..

My suggestion would be to try some very light nutes, maybe 1/4 strength of recommended levels on the bottle. Looks like they need some calmag to me, but def some food should do the trick.

We had to start light nutes before the 3rd node fully popped. Our leaves were turning yellow like yours. The cotyledons were dying off sooner than expected. It seems to be helping ours, but we are using DWC instead of soil. We do need to get some cal mag though. We did 1/8th the strength of GH Flora Trio. We upped the dosage just today to 1/4 strength. Our babies were hungry early.
