they are 12 inch pots i give about 1/2 gal to every 3-4 days when the top couple of inches are dry
should i just pull the catch pan out of em and see if it will drian some let it dry out on its own from there
I dont know how big 12" pots are but if its not a 5 gallon pot half a gallon is way to much. I give max 2L to my 5 gallon plants and thats 1x a week if not a little longer.
And as for the catch pan, if it sits right up under the pot then yes that could be an issue because it could be wicking the water and run off back up into the soil/pot. Which both explains why your plants are flipping on you
