Does the yellowing between the veins on these lower leaves look like a magnesium deficiency?

I agree, looks like mag. Be careful when removing leaves as if the deficiency is not corrected she will start taking nutrients from another leaf. Causing more damage to the plant. I'd leave them on for a a little longer in future. You can cut the dead bits off without issue, if you like. Hope this helps 🙂

Thank you @InspireMe and @hashy for your feedback, it was very helpful. I did some further research and agree with your opinions that this is Mg def. the pH is 6.5 so I'm quite confident that they just need some Mg. Fed Cal-Mag a couple days ago for the first time and I think the spread of the yellowing has slowed. Should be back on track soon, thanks again!
