Grow note

You should always water the entire pot. Don't overthink it. if you think it's been overfed and need to dilute the substrate a bit, the extra water-only irrigations are a good idea. Remember to adjust your formula going forward to avoid the problem next time. quicker dry times aren't necessarily a good thing, unless it's taking 3 weeks to dry and you are growing mold in the meantime. If it's not taking longer than 2 weeks, you really don't need to do that, either, and it's possible a faster dry time (if extreme) reduces quality of end result. how often you fertigate vs irrigate is simply a matter of how concentrated the fertigation is. More than one way to skin that cat.

When growing in soil, you should never fertilize every time you irrigate. Personally, I use a schedule of plain water/plain water/feed/plain water/plain water/feed.........for 35 years now and it works for me. However, water/feed/water/feed seems popular on this site, but the plants often look over fed to me.
