Thanks for the informative response! I’ll have to look into all of that. I really wish I was in bigger pots. I knew deep down 5 gallon wouldn’t quite cut it for set it and forget it. I just wasn’t sure how soon I would have the room.
This is the current state of the 3 showing signs. They all look like this
Looks as if it’s going light green from the inside out. Lower leaves look better then the top, with signs just starting in the veins .Wondering if I have excess P or some kind of lock out
