@dahoola, thanks. This is my first seed order. 15 years of bag seeds, selecting, crossing. It will be nice to try feminized. This was a freebie. I'll be growing The Plug- Spamoni, and Barneys Farms- Gorilla Zkittlez.
@maplemeadtheforestnweed, the one in the back was a severe cal-mag issue. Plus it got moved a lot between LED and HPS. For future reference N abundance is dark green. My gorilla zkittlez has a N abundance ice you want a reference. Yellowing can be a lot of things. In this case its N deficiency and it's natural life cycle combined with poor air circulation.
