Ph issues?

Cannabis plant roots in soil absorb nutrients best within the 6-7 pH range, while plants grown in soil-less setups like hydroponics or in coco coir prefer it a bit lower to between 5.5-6.5 pH. In soil, 6.3-6.8 pH seems to work best to prevent nutrient deficiencies. https://www.growweedeasy.com/cannabis-nutrient-deficiencies-ph-picture-guide

I agree with grannie. Give your soils a super flush. Also, make sure you give the plant just water every other feeding. Salts build up in soil when there isn't enough water to get rid of or dilute it. Soil water tends to do a good job at holding on to salt. If your soil really is living, you may want to stick around your plants after you flush, or at least keep checking on them. Soil that saturated with water tends to make worms want to bail out of the pot.

You need to do a good, hard, solid flush here.... run 3x the pot volume of pH'd water through each pot.... so if you're growing in a 3 gallon pot, you'd run 9 gallons of pH'd water through each and check the pH of the runoff as you get to that last gallon - if it's STILL high, keep flushing until the runoff is where you want it to be (about 6.0-6.5) .... She's obviously got a lot of nute/salt built up in her and doing what you're doing isn't (obviously) helping... When she's dry, you can give her another feed but always make sure you've got whatever you're giving her pH'd properly. If you use a pH pen, make sure it's calibrated. And when you water, make sure you get at least a 10-20% runoff to keep the nutes/salts from building up. Good luck...

My runoff shows my soil ph is high

You are feeding 5.5ph in soil? Unless there is something funky with the line you are running that is way too low. Should be aiming for 6.5 (anywhere between 6-7 is good)
