Your plants look pretty good overall. It seems like your conditions are fine for the most part. Many of the markings you show on the new pics really look like they are from past overwatering imo. Looks like it's from awhile ago though like around a week or two. Sounds like you're watering fine now though from how you explain it ?
I'm not too sure a couple of them still look to be a little sick but the other look like they are bouncing back. I will post some more pictures today. Thank you, I believe it was a Mag deficiency
I'm about to do a watering, feeding on some I will do a update with each plant. most look absolutely amazing, just a couple responded weird to last feeeding
Keep a close eye on everything we’re touching on. Your pH seems good to me. Keep the nutrients as directed. Don’t make too many sudden changes. If it were my grow, I’d remove every leaf that is showing signs and then carefully watch the remainder for a continuation of the issue on the same plants. Patience could be key here.
I suppose it could be a Ca deficiency; early onset. I assume you're growing in soil(?). Then why only 4 of 16 if they're all getting the same of everything?? Before you dump "panic" nutes, check your water pH and soil pH on the regular. Bad pH can really upset nutrient uptake. Your soil might already have what it needs for the grow to thrive, but a possible pH issue will never allow the plants to get what they need from the soil. My well here in WA. is 8.5 so I pH down to about 6.4-6.5 before I water, every watering. My soil sits at a consistent 6.9-7.0 pH. No nutrition issues ever, from seed to take down.
I would seriously inspect all your plants for what may be a pest outbreak. Use a magnifying glass if need be. Look for tiny bugs, eggs or egg cases and pest skin molts; especially under the affected and larger non-affected leaves.
The PH for runoff and for feeding always stays between 6.2 - 6.5, I use PH perfect nutrient line by AN but I still check for my logging. I checked the damaged leaves for any signs of pest and the grow room and other plants. No signs indicating pests. I'm concerned this is a toxicity or deficiency or maybe signs of both.
the only time my humidity drops below 30% or my temp. rises above 80 Fahrenheit is when I have to do work in the tent. Or if the humidifiers run out of water while I am asleep. I am running two humidifiers, I live in Las Vegas N.V. So it is very hot inside garage. 118 Fahrenheit, so the tents heat up fast. Currently for feedings and LST I take one plant out at a time and do the work inside the house.
These plants are due for a feeding today, I'm waiting until later until it cools down a bit and I'm going to look at each one and do a separate feeding for each. That is what I typically do

dont know if im allowed to post links from youtube videos. if not you can delete my post . i just came across a nice video so maybe this will help you even more . https://www.youtube.com/watch?v=KgPvFffsc2I&list=PLBpWI4HLQdwZJxEezrm3R9Q8ES-nVlMuy&index=18&t=0s

How come you plucked the leaves off of the plant? Can you provide some more information so we can properly diagnose?
What strain is it?
Is it in Veg or Flower stage?
If in Veg, for how long?
If in Flower stage, For how long?
Indoor or outdoor?
Soil, Soilless or Hydro?
If soil/soilless, what is in your mix?
If soil/soilless, what size pot?
Size of grow space (LxWxH)?
Make and model of grow light?
Temperature in the environment?
Humidity in the environment?
PH of medium or reservoir?
PPM of medium or reservoir?
Any Pests?
How often are you watering?
Type and strength of nutrients used?
Currently I’m letting the soil dry up a bit longer. I plan to just do a calmag feeding on ones showing issues
