I watered the plant only with nitrogen and calmag.

at first I thought the symptoms were calmag deficiency and I did calmag irrigation 2 times. but the symptoms kept multiplying. I watered it with bloom fertilizers for the first time yesterday. do you think the problem is potassium deficiency?

do the leaf edges lift up when the temperature is low?
lights on: 71-72F
off; 62-64F
ligts time: 20/4
Not typically but light stress can look like many things and your not matching your environment to the amount of light they are getting.
There's a whole bunch of factors that need to be in the right parameters to allow the plant to thrive, your temps are too cold for the plant to metabolise properly, that causes stress , also certain nutrient won't be absorbed properly, plant won't transpire enough .
You using led which doesn't add much radiant heat, so leaf surface temps are too low.
