Without knowing shit about your pH, food I'm going to go with mg def. If so easy fix, add a pinch of epsome salt to a gallon of water along with your food and change the rez with it. Save a little bit and water it down to 30% strength and add a drop of dish detergent and spray it on their leafs for a few days now while you wait for them to improve. The leafs won't look better that are already damage but new growth should be fine.
