Canoeing of the leaves is an indication that your ph is off. (the lower fans are canoeing, pix 3) The yellowing of the leaves above the canoeing leaves is the nutrient lockout as a direct result of the ph problem, and adding nutrients won't help. Perhaps after you get the ph figured-out, you can spray them with a weak (1/4 strength) solution of your nutes.

You'll need to adjust the ph of your water, flush well, and try to find a nutrient schedule that allows one or two feedings a week, rather than daily. And yes...there may be an underwatering problem here, too.

If they've been in the same soil for months, it may not be able to retain moisture. Adding 1 tsp of non-antibiotic dishsoap per gallon of properly ph'd water, will help to act as a surfactant* and allow better absorption. One treatment is all that is usually necessary. Also, sitting in the same soil that long can deplete the lime in the soil, which will add to existing ph issues.
