DWC / pH 5.7 / EC 0.64 / Maxibloom and Liquid Silicon / Res temps = in good range / 20 days in reservoir
Here's how they look now after a daytime rally where I thought everything was going to be fine - they looked back to normal. As the day's gone on though, they've started to wilt again...
UPDATE:
I’m only using GH Maxibloom and Liquid Silicon (as a pH up but it obviously doubles up as a perfect plant nute).
Plants are growing okay - slower than I thought but that’s more about me expecting them to turn into trees within two weeks :D
What a day...been concerned about res temps all day. They were around 71-72 (assuming my TDS/temp meter is fully accurate - I'm not sure it is)...
Then I've just started to smell a mild whiffy smell from the res - possibly the beginnings of root rot, even though I don't have any visible roots...
I don’t think it’s damping off tbh - they’d be stretched and drooping. I agree with @THT.
That said, Google ‘damping off’ just so you can learn how to avoid it
My hydro is dry on the top but slightly submerged at the bottom. I'm reluctant to water the top because I think the root riots are still a little wetter than they should be, so I'm also waiting for them to lose some of their moisture. Is this okay, or should I dig up the hydroton and squeeze...
Still no visible growth not sure why. Maybe root riot too wet.
Res temp: 21.8 (18.4 yest)
pH: 6.11 (increased since yest)
EC: can’t remember exact but decreased
PPM: as above
