Looks like too low a humidity. I had plants that go like that when my room is filled with the small pots. As soon as I tranplant into the larger pots in increased water increases humidity and all is soon well.

I agree with someone else in this thread who said to drop the additives and use just canna a/b until things settle out. Too late now, but I don't recommend flushing with straight water, it just stresses the plant in another way. I've had better success flushing my plant with feed solution until runoff equals input. I'll do this over a few days and adjust my feed strength if the runoff numbers are consistently off. 600 ppm sounds a little low, but then I grow under a 600w, not a 150. Try not to sweat the daily runoff pH too much, that way lies madness. Coco suppliers state repeatedly that runoff pH readings are erroneous. Parts of the plant that got hit hard, especially down low, won't recover. Them's the breaks.
