Aphids, mildew/mold, or neither?

First grow woes... Very much debating an early harvest (was going to be next week or the week after at the latest). I looked all over and didn’t see any bugs underneath. I’m also fighting a ph of 7.4 that isn’t helping much, but it is trending down now. Any help would be greatly appreciated. Take a look see what you think. Thanks in advance y’all.

P.S. I’m aware of the nutrient burn look on the leaves, that problem is now mostly fixed.

could be some aphids. doesn't look like any PM or mold the dark coloring looks more like purple to me. genetic expression or maybe cold temps.

overall it looks good to me. the buds don't look that far off in that pic also. good job on your first grow.


try this at harvest if you wanna wash off any dead bugs / PM

Wouldn’t worry about it unless it spreads. Is it on the surface of the leaves? Does it disappear if you blow on it?
