COCO COIR Help! PH too low, can't fix!

Hi my name is Ann, I am new to growing autoflowers in Cocoa and I bought a new feeding system called [h=1]Advanced Nutrients Ph Sensi Grow Coco Part a B Soil Amendments 1 L[/h] [h=1]Advanced Nutrients Ph Sensi Bloom Coco Part a B Soil.[/h] I also I've been having problems with pH levels and wanted to cut that stuff out completely because of all the frustration. My tap water comes out at a pH reading of 7 and when I mix 1/4 strengths part A and Part B of this feeding system Plus quarter teaspoon of Cal Mag right off the top the pH is around 5 from what I've learned is too low for Auto grow right off the bat, and the runoff is off the chart 4 or more. I got scared and flushed it with regular tap water with a pH of 7 probably like 5 times until the very last of the runoff wasn't quite so acidic still bad but better than what it was. Second feeding after the flesh dried somewhat exactly the same thing happened so I flushed it and flushed it again, and now come feeding time I don't know what to do. I'm thinking just watering with my tap water each time until the pH correct itself. If anyone has any suggestions, they would be more than welcome. PS I contacted the company that sells this feeding system and ask them if there is some kind of trick to this no pH system and if not I'd like my money back! I was feeding the three step system of the Flora grow and just couldn't seem to get the pH right going in and coming out, so that's why I tried this new system. It's very expensive, there is the grow two-part system and the floral two-part system a total of 4 bottles cost me $65. What a joke! Hopefully the joke isn't on me. Please help with some suggestions before my auto babies croak
 
For advanced nutrients pH system to work correctly they need to be mixed with r/o water not tap.

All r/o is 7.0 pH neutral. Once r/o is exposed to air it drops to 5.5 pH. The advanced nutrients mixed correctly with r/o should pH at 5.7 or 5.8 every time. If you switch to r/o and use the nutrients exactly you will never have issues. Nor have to adjust pH again.
 
The potassium in pH up and/or Protekt is very beneficial anytime the plant is growing.

You are looking for the Ph to drift and not worry so much about exact numbers.

pH ranges:
  • Seedlings, Early Sprouts – 5.5
  • Vegetation Stage – 5.8
  • Pre-Flower (stretch)- 5.9
  • Blooming Stage – 6.0 to 6.2
  • last weeks Bloom/Ripening 6.3 to 6.4
I generally accomplish this but making everything going in a pH of 6.0.

Also, the order you mix could effect it- ad the Cal/Mag first then A &B.

Do you know the pH of the coco before you do anything to it? was is flushed to pH adjust-first?
 
I bought a r/o system for my home because I was dealing with p/h issues as well.

All pH perfects systems work the same. 3 part or 2 parts.
 
I agree. You just need to add ph up after mixing the nutes. The reason why you can’t seem to lower the ph is because the water you are flushing with doesn’t have enough negative ions (or basic ppm) to counteract the high concentration of positive ions (acidic ppm) of your nutrient solution. Did that made sense ? The same reason why one drop of ph Dow or up changes the ph of RO water very aggressively and the same drop in a nutrient solution may not even change it a bit
 
Thank you everyone for your replies, most appreciated. I did not pH the Coco to begin with but I am under the impression it has a pH level of 5.4 to 5.5 right out of the bag.
what is r o water? I I am under the impression that my well water at 7.0 is okay. I liked the video of this two-part feeding system with the perfect pH and if it's that simple I need the RO water!
 
Just out of curiosity why does it say green thumb under my username? I'm a newbie at this and if it's saying that I have a green thumb , that's inaccurate. Just thought I'd put that out there:o
 
R/O is reverse osmosis water its really well filtered through a permeable membrane. You can buy a filter for your home or you can just purchase it. At a culligan store or similar 5 gallons of r/o is a couple bucks.
 
Well water does work but the stuff that makes up the ppm in it reacts with the nutrients which changes pH. Which is why you need to adjust pH with well.
 
It was going to originally going to be a system like that but everyone other than mods are green thumbs.
 
I have recently been speaking with the reps at advanced nutrients and they explained a few things to me about their products.

To guarantee they work it has to be in r/o.

You cannot adjust amounts of nutrients it will throw the pH off. What I mean by that is you cannot add full dose of your 2 part and half a dose of cal/mag your pH will not come out correct. But if you do adjust you have to adjust everything equally for the system to work.

So say you put full dose of recommended 2 part. That means any additive added has to be full dose as well.

But say you cut the 2 part in half. That means all additives half to be cut on half equally or pH will become off.

Also I recommend finding the feeding schedule that best suits your needs and follow the order of additives. They also mentioned incorrect order will throw it off.

You dont have to have all the additives from their line for it to work either. You can run it with only bits and pieces of it. But the ones you use should still be mixed in order of the feeding chart. To avoid issues.

Interesting maybe I goofed up throwing off my feed chart. Do they recommend a flush and continue nutes if you used a different combo?
 
You should be okay unless you are showing some issues. The different levels wont make your plant sick. You can do what ever levels you want. The levels just effect the pH system. All changing the levels does is make it so you have to add pH up or down instead of the nutes doing it themselves. if that makes sense.
 
Exactly the nutes will still feed the plant. Just a tad bit more work. What products of theirs do you use?
