Hey Cozmo, plants are looking GREAT man. I tried to get a few pictures of the watering process, but it was really hard to see so I did not upload, but maybe you can catch what I am saying with these. This is a 1.75 gallon. You can see how deep the soil is from the top. Every OTHER week I will fill this to the line you see inside the pot if you look to the right of the photo or about 1 inch covering the surface of the soil completely with water, which is usually about 1/3 to 1/2 gallon of water.

I am giving it 1/4 to 1/3 of the total capacity of the pot itself (2 gallon pot). You are in 1 gallon so you are looking at 32 oz. which is 2 of these.

I do not water with Aquafina, it is just an easy way to measure how much water I put in. After I pour all that water in I am waiting for run off. If I get runoff almost immediately, like while I am pouring the water in, thats not good. It means its running down the sides and not absorbing into the roots. It should take a few seconds and should start as a TRICKLE, not just start flowing out the holes on the bottom of the pot. If it does, its running down the sides, which again is not good.
So if I water like that on Saturday, I will not even start thinking of watering till Wednesday, that's when I start checking weight, dry/damp of soil, how does the plant look. It may be Thursday, Friday, or Saturday before I actually water again. After I give that much water I pick up the pot to notice how heavy it is FULLY WATERED. Now I have a point of reference for when I recheck it 4 days later. So if it is lighter and needs watering again by Wednesday I may give it 1 whole water bottle full (16oz for me 8oz for you), or if it still feels heavy I may wait, but by that Saturday (7 days after heavy water), it will get a whole bottle no matter what, because it needs oxygen in the soil, it needs a recharge. Then water again on Wednesday and it will be ready for heavy water on Saturday again, completing a two week cycle. As the plant gets bigger in that same pot the cycle will change as well, To watering Saturday Heavy, then normal 1 bottle Tuesday, Thursday, Saturday, Tuesday, Thursday, Saturday Heavy again for the cycle.
Your cycle in a 1 gal pot would be 2 full water bottles (32 oz or 2 pints) on Saturday (Heavy), then 1/2 bottle (8oz or 1/2 a pint) Wednesday, Saturday, Wednesday Saturday (Heavy again 2 bottles). The main thing for you is your run off speed right now, how fast do you start to get run off when watering? Immediately not good, small trickle 4-5 seconds after water seeps in and soil settles looking good. Also what does your soil do when you water? Does it rise and then settle back in, meaning dry and full of air, or does it just lay there, saturated and turning to mud?
You have changed some things though, you changed the fan airflow so the girls are dancing now, which means transpiring plants, which is what you want. The bags will by drying out more quickly as well with the added airflow. They will be using the water you are giving them now. You may want to build a berm around the edges of the pot, make the dirt higher on the perimeter of the pot so it focuses the water towards the center where the main stalk comes out of your soil, especially if you notice quick or heavy run off.
This is not exact or even the best, its what works for me, hope it helps.
