Blue Dream, in soil, just starting to flower. One branch has new leaf growth that yellows across middle of leaf and then dies off on end. Growth on this branch has stunted in last couple weeks compared to other branch.
Thanks for looking.

What are you feeding them and how much of it are you feeding how often?

Ph ?

What @LittleDabbie said. If things get too far out of balance in your medium, an abundance of one element can lock out another. If I was to venture a guess with out further info it would be a Ca lockout from too much N...

Okay, thanks gang.
I have fed the plants and I wish I had a better schedule. The last nitrogen would have been some fish meal. Maybe three weeks. Then some fish bone meal and kelp a week or so ago.
Just hit her with some cal mag yesterday, thinking it does look like c-, but the rapid progression concerns me.
Again, really appreciate your helps. I will lay off the new bag of fish meal I just bought.
