I jammed that screenshot straight from nutrient calculator provided by advanced nutrients. I selected base nutes, and entered one gallon. It’s suggests 4ml of each per gallon.
You may want to visit their page and play with the calculator some. Or troll around with some web searches to see if there’s other good suggested data. If you’re adjusting your nute solution to 6.8, water to runoff on your nex feed or watering and check the runoff. You may be feeding plenty and just have a ph issue in your medium.
Best to look close at dosing for sure. Your feed frequency will depend a lot on what’s going on. In some situations rotating feed with watering is good and others not so much.
I think I got some Advanced Nutrients advice from @anon95385719 before, or at least got someone pointed in the right direction. My memory leaves a lot to be desired lol
