your pH and temps sound ok. a bit warm but not bad. im not familiar with your nutes, but reading the labels, the veg is very low in P and 500ppm seems a bit light. are you using a cal mag supplement? i always have Mg deficiencies when using ocean forest. i prefer a longer night cycle to allow the plant to build up hormones better. many people use that schedule and have no issues. it really looks like they are slightly deficient, im not sure if its N or Mg.
