Normal yellowing or deficiency

[Buba Blend]

View attachment 4076548 Hi folks, glad to find yall on the subject. I’ve got an auto compassion lime in soil between week 7 and 8. 11 weeks is what I expect from her. Once I saw preflowering I began pk bloom at 1/4 and slowly increased to 1/2 the stated dosage. Bottom leaves are turning bright green and then yellow. I cut 4off this morning, I expected leaves to turn yellow as she is close to harvest time, isn’t a month a bit too early? She’s got nice buds growing and I’m worried the yellowing will reach the buds.

Looks like a magnesium deficiency.

Thank you, it is as I imagined. So now that I’ve given her some magnesium with phd water, do I keep these big fan leaves? She’s an auto in the middle of her 7th week. Have you any advice to this? Please and thank you

The worst of them won't come back... Go with your gut on the rest. Might give her a couple days.
