how do i flush a plant in the wilma system when others are not ready!?

Hi i have a 4 pot wilma system.... and one problem i have come across now is that i have one plant that seems to be a few weeks ahead in development compared to its sisters (they all started at the same time tho).

How can i flush it? i have pebbles as a grow medium which means there is no water held in the pot after watering so i cant even take it out the wilma and water sepratly

to flush or not to flush is very debaitable. i would just not flush the one plant. (atleast doing it this way will give you your own evidence as to if there is a difference on flushing or not flushing)

I take it all the plants are on one rez (sorry seen a wilma but forget). If it is i have the same issue sometimes. Thats why im really trying to find a great strain for cloning, its takin two years and still lookin lol. Short answer is u don't. I dont run a real hot rez so i will cut back a bit on the nutes, i mean a little like 50 ppms tds but im only running 500-600 to start. I have done both flush and not and honestly i cant taste a difference in the vaporizer, thats not to say its a good or bad thing so be kinda all! Lol

guess its a no flusher then.... thanks for the help
