Please provide exact numbers. What is your PPM of plain water. If you mixed up ~8ml M and 16ml Grow(or bloom)? It could be that your meter’s scale is on the 700scale instead of the 500scale. Yes you want the pH’s to match and that can do done by running more feed through to runoff, but you need to target 5.8-6.0, not 5.6 or 6.5(soil).
I used distilled water with a PPM of 85. Added 2ml grow 2 1 ml micro and 1 ml of bloom. PPM was 1335 run off came out at 835. PH was 5.88 in and 6.2 out.

Might be a good idea to get you a lab grade pH 7 solution. And that will verify meter to be correct or incorrect. Good luck

@kellydans I just ordered another meter last night so hopefully that will give me some better results. Thanks for the advice! Greatly appreciated!!

Ahh. I didn’t realize you were not using the GH line. My volumes/ gallon would be different that yours and since I do not have experience with emerald harvest I cannot provide good guidance on how well it buffers and changes the pH within coco. Emerald should be providing PPM guidance on their packaging or website. If not send them an email.
Yoir pH is within range. As @Killadruid suggested just continue with the proper pH the next feed.

Great thanks again @WickedAle yeah the sheet I have only has ml count but I will get the PPM numbers from them ASAP.
This might be your problem. If your meter is reading 85ppm in distilled water something is amiss. Distilled should be around zero.
@Drinkslinger I just figured because it was Wally World 80 cents a gallon it was not perfect? My PH was not 7 either?
And sorry looked back and it’s 15 not 85

Plastic dissolves in bottled water and will provide a PPM reading. The number is probably real. I would not be afraid to use tap water instead of bottled water. Why the extra expense?
If it was 85 I’d be worried.
@Drinkslinger Drinking plastic from bottled water…you should be worried. Cheap meters are probably ± 50ppm
Dilution is the solution to PPM pollution…
I was just seeing what other water was at. I would like to stick with my pond water actually

I don’t see why not. As long as it’s not stagnant and well aerated you should be fine. You just need to compensate for the PPM and make sure you have the right pH before feeding your plant.
Also make sure ur testing ppms and not your ec
Yep nothing goes in higher than 5.9. 
My EC is waaaaayyyyyy higher lol

K was jw also u dont want that to be to high around 1.5 more then ur ppms
Is it around 2000?
