This book I have says nitrogen deficiency shows as yellowing tips of leaves starting with lower/older leaves. I’m on my first grow too, so I’ll defer to others and am interested to hear what it is.

Discolored Older Fan Leaf I’ve noticed a couple of the older fan leaves have changed colors. These are also fan leaves that unfortunately get pushed up against the spacebucket walls. So I’m curious if this is normal from them being pressed up to the walls or is it a deficiency? Should they be removed?

They say yellowing is normal, but this much?Not sure what to do. First time with autos, and they're around 69 days old. Breeder says 60-70 days mature. Used living soil. The yellow has climbed both plants yet the trichs are only 15-20% amber. Will my girls be okay? What kind of TLC can I give them until harvest? Noob here
