Deficiency

[nLinks12]

Hi,

My autoflowers are a couple of weeks into flower and I started noticing some issues. Some of the leaves have gone a lighter green than normal, and a couple of the leaves are showing brown spots on the leaves. I am growing in coco coir using cal mag + general hydrophobic nutes. Can someone please help me diagnose the issue?

Ph and ppm needed for a reason as to why... But that's a cal/mg deficiency.

I agree, Mg deficiency. Maybe a little P deficient IMO.
