Probably a potassium deficiency since the leaves are not yellowing from center/bottom out. Or if you foliar fed it with something during day time could be burn from that

Looks like a bug attack
2/3 weeks ago it was wet then got hot again, loads of bugs bred up in that time and mold too
I`d spray with a multi- insect/fungicide
If it is a deff I`d bet Potassium and manganese
but I`d bet its thrips or fungus gnats or something like that
The weather hasn't changed that much it's just got a bit Dewey in the night and morning but the suns been good its got to around 45-55 degrees at night Amd yeah I think the humidity is quite high but they have great ventilation and there's always a breeze here 5 miles from the coast, its a huge plant maybe 9ft tall and the other 3 plants there are around 5ft but theyre fine they look great, the problem is that the weather is going to get a lot worse with rain and no sun and it will be a lot colder and I'm not sure she's going to make it and she has a while to go before harvest

Well I don't think its weather related with those temps.. @THE KONASSURE has given the same advice I would give!!
I understand your situation, I live on the north WA coast 2.5 mi. from the ocean. I veg outside then bring em inside to finish flowering..Going to try a couple autos next year.. Good luck!!

What kind of bugs do you think would make marks like that?

I would investigate the strong possibiity of a Calcium deficiency. This is just my opinion and the direction I would personally look in if this was my plant.

Calmag..

Here this may help you diagnose since most of these answers are guesses from what it seems Magnesium is a guess at least get the facts straight if your giving advice. Do not add cal-mag as this is NOT a magnesium issue. This pic will hopefully help guide you. As most plants rarely get a magnesium def.. Also Mag. def. will not have the brown spots random through the leaf.. It is more than likely Manganese, or most likely Potassium. Not magnesium.. If your plant just kind of stopped growing for a minute before these appeared then it is Potassium. If there was no sign of slowing in growth it is probably Manganese. Try adding some kelp extract to a feed or a foliar feed as just a light mist early morning or evening when the sun is not at its peak to avoid burn or into your feed.. That should clear it up. If not then it is definitely Potassium not Manganese. If that is case just get a good nutrient or a booster that has a higher level of Potassium and give a light feed to see if it helps the issue. It is also not a pest problem unless you see them on leaves because these spots are big enough that if it is a pest issue, they are big enough to see. This should usually be a progression def. that happens during flowering but starts as a stop in growth or flower production. Your leaves are still green and there is no curling of the leaves so it would not be an over feeding issue also. That is why Potassium is more than likely the issue. What it could also be, is a overdose of Magnesium so adding Cal-Mag could make it worse FYI

Calcium usually starts on the outside of the leaves with a yellowing.. This is definitely NOT calcium def

If anything this is not a Magnesium Def.. Maybe an overdose of Magnesium in which case adding cal-mag will make it worse

If they are in the ground with no nutrient feed than you would basically get something to add into the water your giving it.. Not really the soil itself.

The last thing I would guess it to be would be a calcium def. But a true Calcium def is not common at all. Although just in the soil it may be,, I would first try to get a regular nutrient like General Hydroponic 3 part feed it with that once to see if it helps as that base feed has calcium and has the basic macro and micro nutrients that should clear it up. I always suggest using a base feed before trying additives like cal mag

A true Calcium def is actually very common. Often overlooked by newbie growers. Its o.k I had to learn also.

Thrips, spider mites who knows

Spider mites are small kinda white dot looking marks. Thrips make like a silver kind of mark I am not saying I know for sure at all but I do not think that it is a bug issue. But never know. That is just my guess

It is usually a calcium uptake issue not a deficiency issue. Which most people think by adding more calcium will fix it.. What you need to do is get more calcium uptake. not by adding more calcium .. It's ok i will teach you.
