You have a mineral deficiency.These yellow spots showed up on some of the leaves is this a nutrient issue or leaf septoria this is on a mature 5 foot plants lots of buds but green.
What do you think @Bill284 ?
I have other plants beside it with no yellow I am hoping it's nothing serious.
As always I appreciate the input Bill ML&R
Most likely cal.
You in soil right?
What are you feeding?
Strength?
Calmag in your plain water 10 minutes before nutrients?
What's your ph going in?
Talk soon my friend.
Stay safe
