Did you find mites and then spray or are you concerned about mites being a possibility?

I am dealing with them in my Vegatable grow but have not seen them in the cannabis room (thankfully). The marks on your leaves don't look like mite damage to me. Usually mites make little specks of orange/brown marks (tiny specks).....

I use a plant oil based spray and it knocks em right down. It has tyme, mint, garlic, clove and onion oil extract and is completely safe for mammals and leaves nothing toxic. On veggies the label says it can be applied up to day of harvest.

Mites are easy to see even without magnification but a good USB microscope helps and they are less than 20 bucks and can work with some phones and tablets. They will also take still photos and video.

Appreciate it no I have not seen mites per se but based on what I’m looking at that’s all I could think it was I figured if it was nute related it would show more towards th end of the leaf and not in the middle

Turn the leaves over and inspect with any kind of magnification you can find look at the tops of the leaves as well. I have had run ins with aphids, mites and thrips and it doesn't look like any of those. Also look at some of the new growth for any symptons....

What you have there is cell breakdown, in between the veins. Thats caused by all sorts of stress factors, but as the edges are going crunchy my bet would be a calcium or magnesium deficiency. I would foliar spray with epsom salts or HG's foliar they have. Try feeding with a cal/mag solution next feed, lower EC value to around 1.3, add cal/mag and that should bump you up to 1.8ish. Also try adjusting your PH as calcium and magnesium are best absorbed between 6-6.5 ph. Hope this helps. Dont worry too much though, its not bugs!

Cal-mag was what I was thinking. But, unless I could see the whole plant, we really can’t tell with a leaf.

What medium are you in and what is your ph

I have grown in a few mediums. Good oil soil is still my fav. To find a good soil took a few years. I settled on Miracle Grow Potting Soil With nutrient beads. For the last 3 seasons or four. Ph stays at 7 for the longest time. Then some pots will become a bit acidic at 6, by then I am harvesting. I recycle that in my outdoor flower befs. Never waste! Also, I use fish emulsion fertilizer. Super Bloom at the beginning of floering on, and I had a few thrips threaten me early. Caught them with Neem oil!

I’m currently using FF strawberry fields and after I posted and read a couple comments I remembered that the medium had a extra nitrogen kick so I’m just going to flush and cut the nitrogen in my feed. My ph was around 6.5

Looks like a nutrient def. most likely potassium (K). I would start with a heavy flush, use a bone marrow flush PH to 6.0 if your in soil. Let the roots dry out then give nutrients. A bone marrow flush helps her absorb K. Our ladies have a difficult time absorbing k. But is a vital nutrient for her well being.
