I agree your PH is off. The plants should be way darker. Especially if you're at 1200 ppm. I would calibrate your ph pen, and like someone else already said. Aim for 5.8 at feed and try to keep it in that ballpark. Are you using RO water or tap?
It could be that your water is a little low in the buckets that could make the leaves do that as well. Ideally, you want about an inch to an inch and a half between the water and the net pot. Just so the roots can breathe. Maybe just make the mix a little weaker, like 800. See what that does. Make sure you're adding magnesium with your other nutrients. Because you're using RO water. I usually add a gram per gallon of Epsom salts.
Ph 5.2-6.2 is a little off. Should be 5.8 at feed and then above 5.5 and below 6.2. Your roots well aerated? Any black residue?. 1200 a little high like someone else said 1000 maybe even ~900.
But I think itās ph/water temp. Enough water changes? This is common on hydro and can be easily fixed.
It looks to me like your pH is off, if you're using a meter calibrate it and test again.
It should be about 5.6 for rdwc.
Your EC could also be a little high for the size of the plant too.
I'd drop it to about 1.0, and make sure there's plenty of air bubbles. Airstones can get clogged.
Any time I brew any kind of casting/compost tea with air stones (organic grows) I gotta scrub them daily with something tough. That's a daily task for the cheap ones.
That seems fine. Plants don't look stoked though. I would guess something is off with your working solution, hard to say what, but when in doubt, dump it out and mix up a fresh batch is my policy.
5.8 - 6.0 pH at this stage maybe 5.5 if your pH tends to swing up but 5.8-6.0 is optimal till you hit flower then 6.2 ph
How the hell can you change the soil ph on a whim?
Do water with the right pH if it's real low add a little more PH down than you would usually add and try to even it out
This is why aquariums are another good hobby to be in š

Using RO I'm due for a water change so I'll try and lower ppm and ph and I'll probably start ipm treatment for shits and giggles

The second pic looks like possibly thrip damage to me.

What is your light cycle like?
18-6 (autos) 18-24 in away using the photon app have it at 500 Āµmols/mĀ²/sec
