Hi Bud! I used exactly the same BioBizz nuts and soil in my first auto grown with RQS seeds and had the exact same issue. Exactly the same spots on the leaves... So I can say I'm 90% sure it is a Calmag issue. I solved it by adding CalMag from BioBizz to the feeding with their recommended dosage = issue solved. My water is pretty soft, around 50/70ppm so almost no Cal or Mag there, so pretty much expected. You are pretty early on the flowering stage so if you act now I don't think it will affect your yield. Good luck!

Anyway, my leaves are getting funky colors and I do wonder, what is causing this? Is this normal? I have used the bloom nutes as in my diary once this week, rest was distilled watering.

yellow/copper appearance in some leaves after first run off watering hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?
