Definitely sounds like a nutrient deficiency, dry ferts should help with that. I wouldnt add the second light, 4wpg is asking for problems even if you have co2. I would add the co2 and dry ferts first and see how everything looks.
BTW, if you are looking for dry ferts I have some for sale, PM me if you are interested.
