Having issue with low run-off


I have a white widow in a 3 gal. smart pot, when i feed or water it i have low run-off. I read where i should get 20% run-off when i feed,i feed one gallon at a time and i get no where near 20% run-off. I’m in 3rd week of flower and i’m wondering if i should feed more water or what is the correct amount for a 3 gallon smart pot at this stage? My humidity range from 30 -36, temp 75-82.


lol you answered your own question add more water it is never an exact amount
