What's up newgrow15 ! Not sure about your spots, otherwise she looks great, is the plant outside, u see any bugs? and are you doing any type of pest management or prevention?
These are indoor under 400w hps. Early in veg I used some neem and azamax due to some slight spider mites. It's been over a month with no sign of them.
I was thinking it was some kind of deficiency because I've barely fed them. They veg from clone for 4 weeks and everyone said fox farms was good for a month. I'm almost on week 3 of flower.
I started some bloom nutrients flora series bloom but at a very small dose.
Here's the thing about the ph so I fed and watered last night. Small dosage of gro for some nitrogen and some flora bloom. I really think my ph probe is off. It was reading 6.6 but my run off was pretty low. Somewhere around 5-5.5.
I checked under the leaves before lights out quickly and didn't notice anything but I will do a more detailed look over when lights on
I was thinking mg deficiency so I did feed it some nutrients with that in it. Now my soil being acidic should i do something immediately to remedy that? Wait till next water and flush? Water regular with a higher ph water?
Ok I used some dolamite lime so hopefully that will do it. I did just go check them out and used a microscope for under the leaves and saw no bugs just those rusty looking/brownish spots. It's only one out of the 4.(for now) fingers crossed. Ph probe read 6.6. Fed last night so maybe they were hungry

1 of my plants has the same problem, started middle fans, now top ones, thinking its mag, leaves are covered in purple blotches and rust spots like yours, let me know if your leaf tips on the affected leaves curl up.

Looks like start of calcium and sulfur deficiency too, similiar too the way my auto started going down hill, got too 54 days without feeding, just ph tap water at 105 ppm and than this happened too my plant 12 days or so in flower, i just fed for the 1st time using gh 3 part, lucas formula with 0.5 ml calmag, all up 240 ppm. My other auto's healthy just one fat hungry one

i second. calcium.
i wouldn't worry about ph. soil buffers, and ff ocean forest is usually on the acidic side, but it should stay between 6.2 and 7.2, which is fine. run-off water will be more acidic, that's normal too.
feed some cal/mag+ or calcite (limestone) and it should clear up. other than that looks fine.

newgrow, what is the temp in the grow space? are you seeing a max temp over 80 degrees F for any long length of time?
Sometimes it'll go slightly over 80 but never above 84 with lights on 12 inches away maybe for the first 3 hours. I run it at night. I fed her yesterday with some flora micro and bloom so that has some calcium as well as mg. should I still do some calmag?
