Looks like the beginning of Ca issues. Spotting on the leaves. some of the yellowing inbetween the veins susgest Mg but its not the only thing that cuases that. Might be hungry over all. No diary linked so hard to tell. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg

What kind of water do you use, and what is your initial EC value? It could be due to too little calcium and magnesium. At least, that's what I think.
