If you are this worried about watering or if you are over watering PK.....
Take your x amount of water.... and divide it by three.....
Feed your Plant Three times a day with smaller amounts of water... It does not have to completely soaked.
Best thing for you it sounds like is a drip feeder. This way you get the same x amount of water, with plenty of oxygen to the roots all day long.
I hand feed 1-3 times a day... Water - feed - water
wait till the top gets dry and continue..
If you know how much your ladies need, then why would you change the routine?
Just saying i go and water when my lady's tell me to water them
The signs are obvious. If you have a healthy plant you will know when you over water.
