This was day 78. Working on dosing with Pfertz, eying my dry ferts. Reading more: Thank you for contacting us! Judging by the picture you've included, your tank would definitely fall into the "heavily planted" criteria. Since you are experiencing signs of potassium deficiency, I would recommend that you increase your n, k, and m dosing to 3 pumps daily. I would leave your p dosing the same, since you have measured consistent residual levels with your current schedule. Also, I wouldn't recommend an increased water-change schedule, since you already have an intensive schedule. Regarding water changes, what is your post-change dosing regimen? Increasing this slightly may also help with your deficiency issues.
