Danky Duck Big Bud ILGM

I've been surprised how quickly this one seems to be growing compared to the last round (which was my first run). I definitely learned a lot last time that should be helping this time. I think I am noticing an early cal-mag deficiency with the slight curling of the leaves - just gave nutes including cal mag today, so will monitor over the next couple of days and maybe give just a little cal-mag water without any other nutes next fertigation. I just got an EC meter thanks to the hubs' Christmas gift certificate to a local grow shop, and immediately realized how very forgiving the last run was!
