Hi all! My Cherry Cola auto flower is about 6 weeks old and has developed this yellowing on the leaves. It seems to me that it needs some Cal-Mag, but I would greatly appreciate some other opinions so I can get her back on track. Thank you!

@JBL this looks like a manganese deficiency. Yellowing at the tips moving in and scorch marks/burn spots. Areas surrounding yellowing still dark green.
That looks like cal.mag
Defency for certain.
Have u checkd pH because pH fluctuating can cause same issues
