flushing plants

I need to flush my plants and looking for someone to confirm how much water to use. I heard 1 gallon water to 1 gallon of soil. Also how many times should this be done. they are watered about every 3 to 4 days, do i flush just durning 1 watering or do i do it for a couple of waterings.

you flush clean ph'd water only with 3 times the capacity of your pots, just keep pouring it through, usually ppl flush 1.5/2 weeks before harvest.

If u need to do it cause nute lockout they do it once and then go back to 1/2 nutes and so on

Why Do You Need To. To Much Nutrients? Or Time To Harvest?

for both, growing lowryder and have about 3 wk to harvest. thought i had nut lockout but didi soil test and have no nitrogen. all of the fan leaves are yellow and most died. since i only have a couple of wk left is it worth puttin some nitrogen in.

A Flush About A Week And a Half Before Harvest. So You Can. No Problem.

so only fush it once in the week and a half or do I do it again if it needs to be watered.
