i'll move it over here just so we don't clog up
@awolace thread , anyways you shouldn't of had a perched water table in a smart pot so just disregard that, but for information sake its say when your running a pot with no drainage and you have a water saturation point where say part of the pot remains submersed or heavily saturated with un-oxygenated water which preventing roots from wanting to growing into it.
But i have a idea that its the opposite as in you were underwatering but correct me if im wrong but i'll read back through your past round later, but have you every done a saturation test of your media to see how much water it can hold ?
If not just take an empty pot and fill with your media of choice then give it a good watering till you have run off, now here the thing allow that pot to sit in a bucket or tray with that run off and let it sit for 30mins or so then come back and see if the pot has sucked it back up or not, if it has then you water some more till you have leftovers in your tray, but then let that pot drain once at that stage till no more runoff and then you know what a full pot feels like, you can also measure how much liquid you put in and take out if wanting to figure out volume wise.
But say in later veg and flowering your watering amount goes up quite a bit and if the roots weren't utilizing everything and you were top watering, makes me wounder if you were under-watering in the later stages.
