11 day auto seedling with Ca def and N tox? What should I do please?

Yes, based on the overall color of the plant I believe it is ok to raise the balanced nutrients to 550 PPM. This should include 50 PPM extra Cal-Mag for the coco so 500+50.

Yes I would up the PH to 6.3 and keep the RH in range the best you can.

...

Would this be taking into account 70 ppm of the tap water i use for feeds? so total 620?

Mag and Ca def doesn't show until a couple weeks after the deficit occurs. Flush your pots with a mild solution ( say 250 ppms ) PH'd to 6.2 . Run a couple gallons through each pot. Check your PH again tomorrow. If needed f lush again. you want to get that PH up to at least 5.8. I see a lot of people who run low ph end up with problems. Feed ph of 6.2 to 6.3 for the rest of you grow should give you good results. Anytime you see a medium PH below 5.6 you know your heading for trouble.
