Have these copper colored spots.what should I make of it. Disease or nutrient problem?
cal mag deficiency
Specifically calcium deficiency. What is your Ph at?
You’re in good hands here, I have same thoughts.
pH is 5.8
Thank you gentlemen!
try letting your pH gradually swing from 5.8 to 6.2,
this will cover your optimum nutrient range.!
if this does not fix it, add a little Cal/Mag to your fert regimen.!
If your in soil 6.2 is on the low end of the good zone. 6.8 is the high end. I keep my plants at 6.4 to 6.6 and shoot to as close as I can get to 6.5.
What media are you using? Soil? Coco? That can have an affect on how much cal mag to use.
Thanks for the input. I’ll bump up my soil pH.
