Ebb and flow/ flowers look sick

Hi RIU,
My plants look sick/ curled up, may I have some help in identifying what’s wrong?
I’ve been trying ebb and flow as my first run,
I have about 33 plants in a 4 x 4 running SOG.
I’ve been vegging it for about 3 weeks, floods 5 times a day. Takes about 15 mins to reach full depth, 15 to drain back
Ppm @ 900 ph 5.8
Temps around 70s RH around 60s

Looks wilted from not enough water. Are the roots getting proper watering? Pump broken? Are you watering enough?

What do the roots look like? What medium? Your 5 times a day floods, those are only during lights on? Man those are some pissed off plants, why didn't you come to us sooner, that didn't happen overnite did it?

Hydroten as medium, clones are in rock wool. 5 times a day during lights on for veg, I just changed it to 3 times a day. I thought me changing out the res would’ve helped it, but i should’ve came for help sooner

Also, whats the water source and feed mix?

I typically flood hydroton every 4 hours when the lights are on. They definitely don't like something about your feed.

Currently using RO water. I’m using Athena nutrients and their 2 part week veg 3 schedule atm.
Here’s a picture of their mix if you’re not too familiar.
Their Grow A is(4-0-1)
And Grow B(1-3-5)

Hmm I have never used those nutrients personally. Do they recommend a cal mag product with the RO?

Honestly if I had to start somewhere it would be pH. Are you sure the pH meter is accurate?

Yes about 2-3ml.
I’m gonna recalibrate it now just to make sure. I change the res weekly, I fill a new batch @ 5.7-5-9, and when it’s time to change it, the ph is around 6.5-6.8
Could it be a res problem/over feeding?
I’m not sure how healthy my roots are lookong

I have seen healthier plants with worse roots, I suspect something about the feed isn't what they want. Have you used these nutes before?
