Leaf tips curling upwards. Showed up in the last 7 days. isn't over watering, I withheld water an extra day and it didn't help. I cut the nutrient solution to 1/2 strength and it seems to have now affected even more leaves. Soil pH 6.2 max temp 80

I think you should be less apprehensive about your girl. Although the PZ photo only frames the main top, apart from the yellowed tips I don't see any disasters, the pistils are a beautiful color and the stigma has no burns. The point is that you have been careful and careful with the water and nutrients and fortunately the plant is in the last stage of flowering. So I advise you to wait and see, remember that the plant is at the last stage of its life cycle, what must be perfect are the buds, not the leaves, which will turn yellow anyway. Keep it up Bro, Ur doing well. 👊 .

Had the same exact issue. Leaves turning yellow at the tips then turning brown and curling. Turned out all I had to do was reduce the nutes with N by half. It had gotten a little toxic. It stopped spreading immediately.

move your light up a little, your getting heat stress, use some kelp and they should rebound, also increase air circulation.

Looks like heat stress if you saying staying below 80 I assume it’s excess light try back off with the lights see if that helps
