Warble has you in the right direction. Looks like a calcium deficiency. Either locked out from salt build up or pH too low.

Calcium shows up in new growth, not big fan leaves on the bottom.
I do agree it could be PH related, but in soil is less likely.
Are you sure they didn't get splashed by nutrient solution? That's all it looks like to me.
Maybe a pic of the whole plant would help.

i agree with snafuu PH issue and also looks like spillage or foliage spry with hot lights on

I don't know about calcium deficiency only being on new growth? Calcium is semi-mobile so it pretty much stays where its at, so when there is a lack of it it will show up in certain spots because it cannot pull from other else where in the plant. And neither of those look like "old" fan leaves on the bottom of the plant. And I bet they start with just a few little spots but by the time they are the size they are in the photos its much more noticeable. Could be too much potassium locking out your calcium as well.

What nutrient line and how much are you feeding?

Read wht you said again. Calcium stays where it's at. That's precisely why it shows up in new growth.
Also, when you quote me saying "old" fan leaves, make sure i actually said that. Just plain rude to put words in my mouth and then argue them.....

Exact same thing on my cherry Og and was caused by it drying. I like to let roots drink the soil dry before watering again to build a good rooting system and I pushed it a little too far. When I noticed it was droopy and leaves started to begin to crisp and yellowish blotches. After watered and it recouped then it turned dry yellow like yours.

This is ripped off wikipedia....
- Nutrients are moved inside a plant to where they are most needed. For example, a plant will try to supply more nutrients to its younger leaves than to its older ones. When nutrients are mobile, symptoms of any deficiency become apparent first on the older leaves. However, not all nutrients are equally mobile. Nitrogen, phosphorus, and potassium are mobile nutrients, while the others have varying degrees of mobility. When a less mobile nutrient is deficient, the younger leaves suffer because the nutrient does not move up to them but stays in the older leaves. This phenomenon is helpful in determining which nutrients a plant may be lacking.
You're assuming the plant continues receiving nutrients at the roots. You can't see the effects of nutrient mobility until you stop providing nutrients.This is ripped off wikipedia....
