Yellow/white spot on sugar leaves

So today I noticed like 3 of the sugar leaves on the bud have yellow whitish spots in the center that are the size almost to the edges. I know I had PH and Mg problems at one point but I have had my PH of the run off around 6.8 and 7.0. Slightly worried now. It's an autoflower WW on day 55 and has about 15 days left until harvest. I just stopped using nutes, so possibly bite burn? Some of the tips were brown and are curling up. Or could it be heat/light issues. It was reaching 85 or so from what my temp was saying, just put AC in so should be good now. I can't up and pics cause at the moment. So is there anything I should do? And will this affect the bud and quality?
