What's Happening to my Glookies? Lower Growth Yellowing with Grey/Light Brown Spots.
Yellowing with grey/light brown spots occurring on the Glookies plants (starting from the tip of the leaf). I believe it may be due to the Fox Farm Ocean Forest soil mix but any advice or input on what is possibly happening is greatly appreciated. Fingers also fused together.

Leaves are turning into dark green with a plastic-like texture
I have 3 ladies in my tent. While the others looking healthy, one of them has a darker green tone with a texture like plastic and shiny. Everything is the same (fertilizer ratio, coco medium), however the one on the picture has a problem. What might be the problem folks? 😩

Heat stress?
Heat stress and can it be saved? Had to go away for a couple days. Hottest days of the summer mid 90's, full sun, but well watered. This is my first ever grow (auto & outdoor) and I expected about 1 week left until harvest. Thanks

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?
I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

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
