Any advice on how to flush properly to remove excess nute buildup and adjust ph runoff, not before harvest, but more like once a month sort of thing, or when you want to rid your soil of all excess N and use straight P-K.
Here is what I currently do, let me know if I should change anything.
I get my water ready with 1/4 strength nutes, ppm of say 300 and ph'd to 6.0.
I begin to water and as it comes out the bottom I take samples, ppm starts out low at say 500, then after a few min of slow watering it spikes up to 1100ppm, ph is steady at about 6.7.
I continue to water until ppm reaches within approx 30% of whats going in, so I flush untill ppm comes out at say 400, but the ph is still at 6.7.
So then I add some extra bloom nutes to my water, ups to ppm to 400, but drops the ph to 4.5.
I continue to water with the ph meter underneath the pot, with the water trickling over the ph meter, I watch the runoffs ph slowly as I water and when it reaches 6.3 I stop watering, take one last sample to check ppm. Its sitting at 500.
So it starts off ph 6.7, 1100ppm, end result is ph 6.3 and ppm of 500.
Is this the proper way to remove excess nutes, and get your ph back to where you want it to be?
