Bud leaves turned black
Top leaves turned brown overnight, That day I did come home to a disturbing temp off 31oC . It’s the black Mini leaves in buds that are worrying me more. lights came on accidentally for two hours so gave her 16hrs dark and back to 12/12 This may have contributed.

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)
I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

Leaves are getting dark
Leaves are getting a little dark and cotyledon seems a little sad. I suspect it is caused by not watering her enough (i was only spraying her with water the first 4days) Any advice?😀

2. Grow with Gorilla Cookie Autoflower seeds. The deficiencies on the back left look like those on the back right, I think phosphorus based on the pictures, and in the front, it's pretty much a mix of everything but extreme. The only bud that smells when you touch it is the one from the back right, the others don't.

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.
Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.
