Can u over water them in flushing?? it seems like flushing them ur overwatering them either way u knw...
Why were you flushing?
Was this just before your harvest?
Was it for nute burn?
The reason there is information about flushing 3 times your pots size (for you that would be around 7gallons) is because it usually takes this amount of plain water to remove the built up salts or excess nutrients.
In answer to your question can you over water them flushing. The quick answer is yes, but only if you constantly flush on a daily basis instead of watering.
There is a big difference with flushing and over watering. Flushing is the process of running alot of water through a plant one 1 perticular day. Over watering is caused by watering every day regardless of whether you need to water or not.
So a single FLUSH will not cause overwatering. But many continual flushes will cause over watering. As will alot of frequent watering.
There is also a big debate about whether to flush using plain water or whether to use a flush additive or whether to even run a weak strength nute flush through them.
This has alot to do with osmotic pressure in the root zone falling to sharply with just plain water which could lead to problems. BUt i wont bore you with all the details. If you want to know i can tell you. Just PM me.
