They look overnuted to me. ph at 6.0 IS low.......and I'm assuming that's from the runoff but it's still too low even going INto the pot.....ph of both should between 6.2-6.8.

Not sure I agree that drilling holes in your pots is going to affect your issue. I'd DEFINITELY stop fertilizing it at all and consider a transplant into some new, ph buffered and correct quality soil. Then check the ph going both in and out until you are sure they are both within the correct range. I love Fox Farms and use it as well but prefer the oceans forest potting soil. Have never tried your type. Just a transplant into good soil can solve a lot of issues.

Good luck.
