Normal yellowing or deficiency

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
