Nope its Nitrogen and its common.
The flowering stretch just ended I assume?
Plants go through a ton of the stuff during Flowering stretch, you can ignore it unless it gets worse, any new leaves fading in any number means she needs feeding.

Hello.. Hope you are well.. Dont worry.. She looks amazing.. Its literally her leaf has used up all its energy and beginning to fade.. Its also a sign of her getting ready to ripen because she's an auto the whole process is just a bit faster.. Well done n stay safe.. 👍🍀

Lower leaves turning yellow is definitely N deficiency..
Don't forget your plant grows and gets bigger and in the beginning doesn't require as much food compared to later when she's bigger.
happy growing

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?Week 2

Yellowing of leaves Week 9Help! 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?Week 9
