led&light burn?

Oh my that’s not looking too great. I’d pull it dry it and check it out. Look at what you did wrong and try to make corrections before starting your new grow.

although the plant is at the same distance from the light after entering the flower. the leaf edges are showing heat symptoms. the temperature is at average values. and then the upper leaves and some large fan leaves turn yellow, dry up, become purple and red.
 
at first I thought that I had deficiencies such as potassium,phosphorus. but I watered it with bloom fertilizer during flowering, and there was no improvement, on the contrary, all the leaves died that way

Could be the roots are fucked from all the stress and it's simply not able to uptake the nutrient.

Could be your ph is so off because your ph meters fucked that it's not uptaking them.

Could be the floors super cold

Could be overfed and locked out

i didn't think there was light either. i was looking for the fault in myself, but after my perfectly progressing pots came into flower, they became like this
 
i paid extra attention after the plants I took the first photo of. my ph meter is adwa12. temperatures are at average values. the salt proportions are average. but in a way I don't understand, my plants are like this
