Need help watering coco

Hey guys.
I grew loong time ago and cant remember everything now.

I planted seedlings into 10L (~2,5gal) pots with 100% canna coco, no perlite. I've been watering them just a bit to not soak the little plants. But now im starting to be afraid of salt buildup. Yesterday I watered biggest plant ( 3th leaves opening) and runoff was 5.9ph 320ppm and i've fed them 600-800ppm 5.8-6.2ph. This was first runoff from any pot.

Im thinking the best would be to water them all with runoff now. Some are still pretty small though. How often would you guys water small plants in big pots? And always till runoff or is it viable to water lighter without runoff? It might have been a mistake to put in large pots straight.

Also got veeery slight leaf curl upwards on few plants. Can this be due to low rh, or is it calcium deficiency starting? lamp 1.2m away (4ft), 600w, one fan oscillating, rh was 45%, dropped to 30's today and saw that leaf curl first time. Most curl on plants closest to oscillating fan. Also watered with higher ec yesterday, 800ppm. ~100ppm calmag, 70ppm water, rest nutes + additives.

Any help is appreciated.

plants are 2,5wk old from seed, biggest are opening 3rd leafset, so they are quite small still. No big leaves on them yet.

I watered with runoff today and its off. Ph 5.7. Watering without runoff was bad idea. Maybe low ph is causing early calcium def.

Now I just need to figure out how often to water. Runoff seems to be the only way, but once a day or once every 2 days?

You're running yourself around in circles testing runoff. It's best to start in small containerd but obviously it's too late for that.

Make sure what you are feeding is at the proper levels and go from there. No idea why you are feeding a seedling 1.6 EC nutrients but that's way too much.

I'll try to look for charger cable for my camera.
They started to grow nicely and were a bit light green with 1-1.2ec so I fed with stronger stuff for 2-3days.
Yeh it was mistake to start in so big buckets. Theyre not topped off completely so maybe 8L of coco, but still. Just gotta survive for few days and it should be ok

Fount the charger after a long battle!
Here are the pics. Camera is old af, hope you can see something.
fifth? pic has the slight curve in leaf
Can't see much colors. I can take more pics when lights out, for now hps stays on. Basically they are very nice green now, new growth has no light green on it. Not overfed green, that smallest plant is a bit i guess

Everybody falls into that camp at one point or another lol you can totally overwater seedlings in coco. Ask me how I know

op from initial seedling stage to where your are now is when you don’t give them nutes (maybe a little further past it), I personally don’t give any nutes until the initial 1-2 weeks. Unless the plant looks like it needs it.
for plants that small I’d keep it at water only. But since you did start feeding I’d take it down a little bit. Maybe to about half and see how they react to it. After all you can’t force feed them. Don’t panic they don’t seem too detrimental just keep an eye on them

Thats sounds like alot of swampness to me. Its only coco, I grew like this long time ago and remember that you can actually overwater in coco, especially small plants.
But ty for tuning in, ill keep that in mind

Don't feed that often listen to BK or someone that actually knows I think like a shot glass of water
