All respect to OldMedUser but we disagree on a # of things here.
That's cuz the pix are shitty and its hard to say. Can you use a flash?
Honestly tho neem is rather benign, as are the epsom salts, when used in proper dilutions. So you're not likely to have issues with either, or both. Still not a bad idea to mist em good between applications to keep any unexpected interaction less likely. Once they dry I'd foliar with epsom at 1t / liter. But like OldMedUser says you could just water with them instead and avoid additional stuff on the leaves. I like to foliar epsom because its so fast-responding, also I don't add the additional salts to my soil.
Mostly your plants are healthy right? What % is affected?
I say its not bugs because it appears you've interveinal chlorosis, and ridged leaves, esp apparent in your third pic. I've just been dealing with this, and epsom salt foliar fixed my problem pronto.
