Help are these plants ok

The lower leaves look like a nitrogen deficiency to me, while the white/light colored spotting could be pests such as spider mites. I would look check the leaves with a microscope for pests if able. If mites I would go neem oil. The nitrogen deficiency could be fixed with some sort of grow booster with nitrogen. The leaves on the bottom may not look as pretty but the new growth is where its at once resolved. Good luck!
