I've had this before. I went through a good number of flushes and different fixes. I had this happen when I used lemon juice, vinegar and bicarb for ph adjusting. I don't bother adjusting it at all now (growin in soil) Also got a problem like this when using plant magic old timers, I wasn't using enough feed in flower. Gave it a few good feeds of bloom + boost and it soon caught up, carried on feeding about 6ml per ltr of bloom + boost and not had this problem since. I'd had it happen on at least 5-6 plants.

Too much fertilizer. What is the source and starting PPM of your water. Water only for the next 7 to 10 days. Add a tablespoon of molasses in 5 days just once.

Don't give her nutes for a while, just water with plain water. You seem to have nute buildup.

Do not feed any nutrients the pot is way too hot. Plain water only.
