I don't think they are dialed in just yet. Would have thought heat stress but your temps are too low. Those are temps taken at canopy level, right?
 
Yes, they are taken at canopy level. I think, It could be over watering. I flood 4.Times a day for 6 minutes. Flood level is about 1 cm below cubes. But rockwool stay moist all day. Roots at the bottom of pots look like spaghetti, they haven't got hairs. Roots are nice white, but without hairs. Today I try cut watering to only one. Let's see.
