Just this guy, ya know?
I'm guessing that's hydro since you are listing EC. It looks like a calcium deficiency to me, 5.8 is right on the border of where the plants stop taking up calcium in hydro from my understanding. I would try raising the reservoir ph to 6.2. You really want it swinging from about 5.8-6.2, that way you can guarantee all nutrients are being absorbed.

Yeah seems like too low pH..

Coco is also extra hungry for calcium and magnesium than other mediums..

Some of those signs are also phosphorous lockout as well because of the pH..

Sort the pH and maybe start spraying under leaves with Epsom salts because a mg def might be a bitch down the line..

You might want to raise your lights up a bit for a day or two as well just to let them chill out on photosynthesis till the root ball is happy again.. :2cents:
