I would up your EC and water less frequent until it has a bigger root mass to cope with more watering more often.
Its not going to hurt to add a cal/mag solution , most coco growers do. I personally don't but always have a bottle available.
When you do water allow plenty of run off.

How often do you feed? When did you start feeding? How old are the plants? What water do you use? Do you ever use plain water? Plants that size in a coco/perlite mix like you have should be fed every day to run off with 1/4 - 1/2 strength nutes, pH'd to 6.0.

Canna coco a+b is on a 500 scale, isn’t it? I would think 0.7 is fine.

The 3 weeks since the seeds poped out, 0.7 ec its about 350 ppm, they look good 2 days ago, then i water them with 10-20% runoff, i put my heater inside the tent, but have a termostate in it temps dont go higher than 24°. I already can see roots on the bottom. I water them 2/3 times a week

I would up the nute strength, add some calmag, and start feeding to run off every day. 2-3 times a week is what you would do in soil, not coco.
Just to give you a comparison, these two plants are 3 weeks old and been fed every day since sprouting.

What is your coco/perlite ratio and do you have plenty of drain holes in the bottom?
