First rdwc run

Hello I haven't had plant issues in a long time but that was in soil. I want to conquer rdwc. What is up with this plant, the rest seem ok although they are all starting to get purple veins in the leaves. But this one is also droopy. I'm using regular tap water starting ec is .3 after nutes the ec is 1.2. I'm using advanced nutrients. The ph is 6.2 up from 5.8 I'm letting it fluctuate a bit. I am using ph down although advanced say there's no need but I'm not sure maybe the ph- is screwing it up. Any help is much appreciated

How is your water temps?
Going sterile?
The purpling could be start of magnesium deficiency/bit too much light than they can handle.
But droopy and leathery looking leaves makes me think like roots might not be all happy campers.
This could lead to the nutrient problems.

Water temps are at 19 degrees 66f now that I put a chiller in today, it was 25/77 for a couple of days. By sterile do you mean no beneficial bacteria? If so then yes, I'm also using oxy plus. I adjusted ph back to 5.8 and added some calmag xtra

Yea and if sterile then usually chlorine of sorts, especially if water temps getting out of hand.
19 is nice, but maybe the 25celcius has made some problems.

Maybe you could have a look to the rootzone of the most droopy one?
Also if the water isn't looking that fresh anymore, airbubbles take longer to pop etc, then there might be some slime growing.

The H202 are fine, but problem is, they aren't too effective with the rates applying and the shelflife is pretty bad after opening (like 6months).

Roots look great nice and clean, it looks fresh.
