Hmmm, I dunno. I don't want don't want to hijack your journal and will message you if that's ok?Yes. The 7 gal is a full watering to run off and then about 32 oz about 7 hours later which is probably close to run off, at least a few drops.
If your soil tilth is right then your roots should absolutely fill a 7 gal fabric pot like a blivot.
And with heavy roots, proper soil and the plants transpiring as they should then twice a day is pretty normal for tiny (under 10 gal) pots.
If you're in flower especially late flower and only watering every 4 days then to me at least something ain't quite right.
The 20 gal i give about 1 to 1.25 gal of water a day which is never to run off.
I don't want them to have run off.
Just a good watering to keep everything moist .
