Flushing before harvest

I have heard it's a good idea to flush your plants 2 weeks before harvest, but what I haven't heard HOW you flush the plants. Do you just water them every other day and stop feeding?

I would like to know also... Never flushed them yet... I can't take outside and use hose...lol...neighbors mite not like that. Or maybe they would,,...

Flush with PH balanced water...

.....to rid the medium of extra nutes and salts. The first few days, dump enough water in there so that several gallons of water come out the bottom of the pot.

This is to rinse the soil/rockwool of excess.

Then just water as normal with the plain water. You can even flush for 3 or more weeks if you have enough green above to keep feeding the buds.

I usually flush 3x my container capacity (5 gallon bucket= 15 gallons of water), scared the crap out of me the first time I did it, that was a LOT of water to be pouring on my spoiled babies.
