We where referring to what you said about the gallon of neuts plus the extra 3/4 gallon (not doing that just use the full gallon of neut water)
I believe what nick is saying is don’t worry about only 15% runoff, you have now dried out your pot and are ready to start a fresh watering cycle. You’ll want full saturation of the medium. So I’d do 1/4 of the water (or as much needed to lace a 1/2” of water on top of the soil and wait 10 minutes, then do another 1/4 of the gallon. Repeat that till the gallon is gone even if it’s coming out the bottom just keep getting rid of the runoff until she stops dripping
Nick wants you to fully saturate the soil, and then you’ll wait to water again and do the same thing once the pot is fully dry again (light when picked up)
