PH Help??

[JayY2015]

I Have washed my coco with like 30 gallons of water then about 10 gallons of ph water and I cannot get the ph to drop below 6.4 wtf is going on I got canna coco it is supposed to be clean is there a trick to washing this crap or what ?

I just washed one of them with ro water like 7 gallons worth of flushing, run off ph is now 7 lol I tested my ph tester it was all good and the ro water is like 6.1-6.2 ph
I have some spots from what I think is a defiency from the ph being to high idk this is my first time doing this crap and I am going insane lol

If you are reading runoff thinking it represents the mediums pH, then yes you will go crazy. Because runoff pH tells just about zip of the mediums actual pH.

how i do it...
1). fill jug with filtered water
2). add nutes
3). ph water accordingly 5.5-6.0
4). feed plants.
checking runoff doesn't really do jack...and i killed a plant think just like that.
if you have only a few plants and mix your nutes per gallon ~like me~ then you will want to check the ph before every feeding.

IMO dont check the ph of your runoff, but you can check your ppm's to see if your plants are eating enough. GL, just flush and go!

I don't wash my canna coco at all - I mix with perlite right out of the bag and use 1/4 strength MaxiGrow nutes, ph'd to 5.8. Never have a problem and I never check the run-off. Just my opinion.

Like he said bro. Checking the run off pH is highly overrated, and its not an accurate representation of the coco medium. To get a better pH value of the coco do a slurry test. But the only time I check my Coco's pH is when I'm having savage defiencies, which is rare.
Do like I do. Use drip clean (house and garden) EVERY feeding, and you'll really never have to flush/rinse, until pre-harvest.
Good luck on your grow bro
