Hey Mate,
these ammendments are quite nutritious, I think you overdid it by giving more grow-nutes!
I had a test run with the Super-Bud-Mix from Zamnesia because I couldn´t believe that they should last
the entire grow. I just added some benficials and bloom boosters to pH´d water but no NPK fertiliser.
And yes, the clawing is a sign of excess.
Good luck and happy trails for the rest of the way!💪
