I see what you mean, I think that's more a organic soil type medium, with regular coco/perlite you need to arrange the ec/ph I think, canna coco for example has an ec of 0.0.

First you should address why your pH going out is higher than your pH going in...especially if you're running in coco. If you're feeding correctly and all is well, they should almost mirror one another. Especially if you're feeding 3 times a day.
Your plants look a little short on Mg (which you should be feeding daily if you're in coco) and Ca, which you should also be feeding daily. If it were me, I'd sort out the pH issue and feed more Mg and Ca, and see what happens. God bless

Here's a quick update, the additional food, Calmag, and more frequent watering seem to have done the trick. Its a jungle out there!
