How is it getting to 5ph? did you knock it down that far? So its coco but driven by a system and extra air stones. hhhhm now could this be another case of the air stones messing with ph i wonder. probs not lol....
However, if i gave my plants in coco 5ph they would lock out, i have had to flush a few times due to salt build dropping the ph, i have not been over doing the feed either. At the moment i am giving 5.9ph and they are healthy.
I wouldnt start over they look good other than the color, fix the nute issues and ph and they be fine. I would raise that lamp a few inches though lad, just to back off the growth speed and over all stress on the plants.
