PH'D WATER AT 6.5 BUT RUNOFF COMES OUT AT 7.0?

Seeing the whole plant does help a lot, based on those leaves you showed at first I was expecting a much sadder looking plant.

Overall it does just look like nutrient burn to me, not heat stress. Nutrient burn usually starts at the bottom of the plant and works up, deficiencies start at the top and work down, and something like heat stress would most likely affect the entire plant.

Cut way back on all the things you have been giving her and she should be ok. It looks like you still have some time until real flowering starts. I am in mid Michigan and my outdoor plants are just showing pistols. With all the amendments you put in the soil it might not need any additional feeding for quite some time.

PPM and PH of your runoff in soil is not as useful a tool as for coco growers but keeping an eye on them never hurts.

Good luck!

Well now that you've posted a picture of the entire plant it puts things in a new perspective. If those were just the bottom leaves it's not that bad since the rest of the plant looks decent. I'd just be careful adding too much.

I don't know why anyone would tell you to pH your water to 5.8 if you're growing in soil. Don't listen to them.

You're doing good. Plant doesn't look bad. Bottom leaves on plants that size die off. They are not going to stay pristine forever. Just like other plants leaves on cannabis are going to die and fall off as the plant grows. The plant looks healthy and you should get a good harvest. I don't see any serious problems. from the pictures of the entire plant.

To match the low pH of rainwater maybe, all outdoor grows run between 5-5.5 if not shielded from rain and that being their main supply but someone might take that a bit too literally and start adjusting their tap to suit.
