overwatering, or just light magnesium issue and proper FEED hunger.
If ph is right 6.3-6.4, you water every 3-4 days with small run off and in intervals - she is hungry.
if you do anything otherwise - root issue and magnesium deficiency.

Looks a little deficient in everything if your ph is good—- try a good ole compost tea and back to normal feeding!
