I actually didn't think of pests... But it doesn't seem to be leafhoppers as there's no mark on the underside. The good thing is that the spotting hasn't changed or spread and I'm not seeing more signs of nutrient problems.
As the title suggests, I have a few yellow spots that popped up on the sugar leaves on 2 or 3 bud sites. I've done a ton of research, but can't quite figure out what the issue is or whether or not to be concerned. I'm in the 2nd half of flowering and some fan leaves/lower leaves are yellowing...
