Been trying to understand what my plants are telling me but I'm still unsure. Here are leaves from two different plants. They only appear on the bottom part.

Yeah I've tried using charts to identify the problem but none of them looks like the left leaf on my picture. I first thought it could be sulfur since the veins are turning yellow first but like I said this only shows on the bottom leaves.

I understand, so many problems are similar. If those leaves aren't getting light the plant will shed them.

With no info on your grow... Look at Mg. And save this book.

I have a similar problem except it has spread to the upper leaves, CalMag was recommended so I added that and I am awaiting the outcome.

no,that would be seen on new growth not older leaves.
looks like it started in the middle and its going outwards,thats a clue. Mg usually strts outside and moves in .

Let me know how it turns out, I've been using cal mag but only in small amounts.

Also, could it be related to pH?

IDK, why don't you drop a hint about your pH and maybe you medium for starters and maybe we'll find out? Picture of the whole plant too

Typically people want to know all the particulars: soil or hydro/pH/temps/humidity/light/ and a plant picture in normal light, not under blurples.
