Had to tell from the pics, I think it's more likely to be bacterial/fungal.

You often can't apart from removing effected plans. Need to make their environment as healthy as possible, whats your growth like? Generally really healthy well fed plants have strong immunity to problems.

Almost all of the lettuce in my system has that look. I think it’s either nutrient deficiency (doubtful) or temp. Lettuce likes things a bit cooler and I try to keep my water warm. It all tastes great so I don’t worry about it.

You'll often get spots like this if you've had splashing or rain on the leaves. Try to keep the leaves dry if you can. I think it's probably a bacterial or fungal problem as was mentioned earlier but many organisms are spread by water droplets.
