Deficiency?
Fusionanswered grow question 5y ago
It's a pH flux. Need to drop your pH more when watering. Bit of Calcium won't hurt her either.

Hi there!
Check your pH and make sure you don't have any lockouts or anything. That yellowing starting from the tips looks like a Potassium (K) Deficiency but those curling leaves and darker green says you might have something else too.
