What soil are you using? What nutrients are you using? How much nutrients have you been feeding? and on what kind of feeding schedule?

Need more info.
but overall, with absolutely no info,
I would go with what Satori said, best educated guess with absolutely no info just looking at the pics they need Mg.
or you have been overwatering on and off and is just not apparent in the photos this moment.

Perhaps all the nutrient salts you fed, even though feeding at proper pH, has driven the pH in the medium down acidic out of range, and now you have Mg deficiency. Just a guess. I don't know.
