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.

Yellowing of leaves Week 9 Help! Is it normal to have such yellowing Week 9? The buds are still green, but the bigger older leaves are quite yellow. Same strain different plant still very very green. Might be the difference between topping an auto and not topping an auto?

When to start using Cal Mag?Tomorrow my Bruce Banner plants will be 2 weeks old. One plant is showing some yellow on the left side of one leaf. No yellow on any leaf tips and no claws. I believe I may have been under watering. My question is should I/can I start using Cal Mag or should I wait longer?
