Hi growers,
its my first time growing in coco and I have some doubts.
These are my Parmanent Marker clones, 7 days after potting. For some reason the edges of the leaves are raised on all plants, some of the leaves also have pale green colour between the veins, nothing crazy but the camera makes it way less visible.

Here is the detailed info of the setup.
Lights - Marshydro TS3000, intensity 25% sitting approximately one meter above the plants.
Temps - 25°C day, 23°C night.
rH - 60% day and night.
Leaf temp - 23.5°C day.
VPD - around 0.95kPa.
Soil - Canna Coco + Perlite (70/30).
Nutes - Canna Coco A + B, Calmag and Rhizotonic.
One oscillating fan blowing at the top of the tent, no direct wind at the plants.

Plants are in 0.5 plastic pots just until they develop bigger roots. I water them every morning starting with .1EC bottled spring water, adding Calmag to .4EC, then adding A + B to 1.2EC. pH is 5.9 - 6.1
Runoff is .9EC and 6.4pH.

Im not sure if the raised edges are signs of light / heat / humidity stress or just high evaporating activity. Also im not really sure about my feedings, the pale colour between veins worries me a little.

I would appreciate your opinion on the raised edges of the leaves, as well as opinions on watering schedule in coco.
I've read that you cannot overwater coco and you need to feed with every watering and keep the coco at 90%-100% saturation, so i water every day even though the coco definitely doesnt dry back, the pots are somewhat lighter but i get around 40ml runoff when watering with 100ml.
Is my feeding and watering okay for such little plants?

Thanks for all your opinions and responses. :)

I think your clones are just having trouble taking in enough water for all the foliage they have. This is why many growers remove a lot of the leaves and then snip the tips of the leaves they keep. The size of the roots do not match the size of the plant yet.

the only time i have seen that is because of too much nutrients , i struggled with problems like this for 2 years with autos in coco, see pic, now ive gone back to photos in soil i havent had one issue.
they dont need calmag too much, in fact calcium competes with nitrogen on the roots space and its nitrogen you want most of now. the three fingered leaves are a sign of being stressed as well i think. when were you going to transplant them ?

Seeing the edge curl and interveinal yellowing, I'd back off the light.
