A few of my plants, all different strains, have started to show a weird yellow pattern on the bottom leaves. At first I thought it was just because they were dying off but now the pattern seems to be slowly creeping up to higher leaves. I have tried looking this up, maybe I'm just not phrasing the questions correctly, anyways anyone know what this is and how to correct it? Thanks in advance.
New Grower Yellow pattern on bottom leaves?

What medium are you using? Have you feed yet? How old are the seedlings. Could simply need a good feed, but let's get some more details. Temp, humidity, etc.
Wouldn't hurt to see the whole plant.
I am using coco coir and this seedling in particular is stunted, It is an OG Kush day 49. Although it has been stunted the whole way is hasn't shown any symptoms until this. the temp stays around 75 and I am still waiting for my RH meter every time I try to order one something goes wrong. I started feeding about week 5 because that's when it seemed to be big enough to require nutes. Oh also I have attached a full plant picture.
Check real close for insects both top and under leaves.
Okay, your in coco. You must feed with every water and get good run off, shoot for pH 5.8. are you using an EC/ppm meter? What nutes do you feed and how much?
Bugs? Indoors? omg no!
I didn't know what a ppm meter was. I am shooting for that ph. Right now I am using grow more nutrients for the veg stage. I am using about a third of the required dose at the moment.
A pH meter is critical in Coco a parts per million meter is important. For one thing your background water is going to have some nutrients in it no matter where you live. It's important to know how much nutrient I'm going to call them salts from now on or in your background water. Because, you're going to add salts and you're going to want to stay below a certain part per million level. Your nutrients are all mineral salts.
On the left side of your schedule you will see the part per million targets. That means with your background part per million and the nutrients you put in you don't want to exceed those maximum levels. I never achieve those maximum levels and I grow coco. I don't however, use that nutrient line. I've never actually heard of it before but it appears to be a good line.
So to answer your original question about those funky looking leaves down on the bottom of your plant. I think you've been a little underfed and those bottom leaves are where mobile nutrients will be stored at for use by the plant. It's good to have the plant using those nutrients in the lower leaves when your later in flower it's not so good when you're at the stage growth.
I believe you need to feed more and get good runoff. I'm a little hesitant to give you that advice without knowing more about your background water and your nutrient levels. But, that's the way it looks to me and I do grow in coco.
Any chance nuted water spilled on the leaf while feeding?
