Small reddish spots all over leaves

This is my first grow, it’s just a bunch of bagseeds outside. They’ve had there issues with spider mites and caterpillars but they’ve overcame everything so far. Admittedly I didn’t know I was supposed to be giving them nutrients until like mid July (all planted in May), but since I’ve started I think I’ve kept them pretty healthy. They are yellowing quite a bit now which is def partially cause of the weather but I also think they’re in a nutrient lockout cause last time I fed them it didn’t make a noticeable difference, but it always has in the past. I usually only feed them when they look like they’re starting to yellow, next grow I’ll do better. These spots just came to my attention, not sure exactly how long they’ve been there. Someone on reddit suggested it was alternaria, but I don’t think it’s that. I keep a fan blowing on them outside, and it’s been relatively cool, breezy, and not too humid in NY. Any advice? The first 3 pics are the same plant, last 2 are both different.

Hey Mike - Do you have any idea what you PH is like in both the soil and water? This looks like calcium def to me - what are you feeding at the moment and what medium are you growing in? Yellowing as a result of weather seems unusual, so if you can give some more info, then I am sure we can work this out. Your newest growth looks a bit greener, so things may already be correcting. She looks ready for an all you can eat buffet!

Not sure what the PH of the water is, it’s just whatever comes from the hose. The water here is pretty decent, but I’m not entirely certain. The only nutrients I’ve given it are some herb nutrients I had for other plants in the garden, it’s main ingredient was nitrogen and the plants seem to have liked it. I’ve given them a handful each like every 2 weeks or so since mid July. All the plants are growing in regular potting soil from Home Depot. Calcium deficiency is what I was thinking too, I’m just anxious to give them more nutrients because their last feeding didn’t seem to do much an idk if it’s lockout from over feeding or if I just didn’t give them enough. Sorry that this grow is so janky lol, i never expected to actually get anywhere with it.
