I'm not good at diagnosing, others will be along. Here is the link to the GWE diagnose sick plants section.

Have you been checking the pH? The pH at the roots being too high or too low is the most common reason you see nutrient deficiencies, because the plant can't properly absorb certain nutrients outside the correct pH range. In soil you want to keep the pH between 6-7.

Also, just a thought but since there's so much yellowing, what's your grow light and how close is it? How much water are you giving at a time? Did anything different happen right before you started seeing the symptoms?

I think they can come back from this with a little TLC!
