flushing soil

i'm wanting to do a quick flush to get the nitrogen out of the soil, why?
on week 8 and fanning leaves still green,
whats the best way? and fastest? there not huge plants and in a 10ltr pots
give them 4 litres of water each last night and another 4 tonight...how many litres should i flush through

you need to double the amount of water you're pushing though the soil.. say for one gallon i ususally flush it with at least 1.5 gallons of water.. you want a steam of water running through until it is pretty much clear. then add nutes for you ahve flushed them all out just make sure you don't over water (meaning wait like 4 -5 days til you water again


its not just ot flush the nitrogen you prob have nute build up.. any pics?

aye your right, just need to flush them. how many litre's all together roughly before you drown a plant ?
sry no photos

i wouldnt flush yet it could be a late finisher are the trichs ready
