Have a look the leaf photo's in Week 12 and tell me what excess/deficiency you see. I think it is a Magnesium deficiency but I'm far from sure. The leaves effected are mainly middle of the plant fan leaves or lower fan leaves on the cola's.

Hi Shaggy. Looks like textbook calcium deficiency. Magnesium looks interveinal chlososis, calcium shows up as brown spots on leaves affected. The requirement and deficieny signs with calcium can be weeks apart meaning your middle leaves needed calcium 2 weeks ago and because it’s not a mobile nutrient as the leaves grow your requirements of calcium or not met hence the spots. Now that you’re adding “cal mag” you shouldn’t have anymore issues. (Calcium is required at 6% magnesium 2% each feed) hope that clears it up for you ;)

Hi @ShaggyGrower, this definitely looks like a Cal/Mag deficiency. I see you already gave her some TNC CalMag, so we'll know very soon! Happy growing :facepunch:
