Mint Plant Issues

[Razoe]

Hey Guys,

So i've been growing mint Hydroponically for a few months now, and these issues have popped up on my plants several times. Can anyone identify what this might be and what is causing the issue?

Well, if those plants were in an inground vegetable garden I would have to say that they are suffering from a micro-nutrient deficiency with possibly a touch of some fungal disease and I would use liquid iron chelate on them and then I would spray with Neem Oil, but since they are not, I don't know what's wrong or how to fix it.
