PH goes up

[BentBuddha]

I have a run2waste system with a 200ltre barrel. I use:

- Advanced Nutrients (recomended ph of 5.6)

- au60 root repair

- fulvic acid

- silica majik

- nutriboost

- advanced nute big bud (powder)

 

I set the PH at 5.6. But when i check back couple of days later it's up to 6.2 -6.3

 

Whats with that?

 

The Advanced nutes website recommends using nitric acid to bring PH down as the stuff most ppl are using reacts with some of the nutes. I might try it out as i'm putting quite a lot in to a 200ltr barrel, and I'am interested if anyone has experience in this

it took me ages to get a grip on ph

 

first get a little air line in your water butt and let bubble for a day .. check ph , add all your required nutes etc ... then bubble some more ....few hours maybe , then check ph and adjust with ph up\down .... get this bang on ..... bubble some more ....few hours then test again .

 

should be good to go ...

HI BB

 

If you use an EC/ppm meter you'll hopefully notice that as your ph rises your Ec/Ppm's drop, this is actually a good way of proving that your gurls are using nutes and that all is good.

Before I had my system dialed I was adding ph down every 3 or 4 days although using canna coco nutes at full strength Im using silicone to bring the ph up.

 

Id also agree with everest this is a good system to use when youve just filed a new res although i test once add nutes and allow to sit overnight before retesting.

Your PH is fine for coco at 6.2 - 6.3, that is where I run mine, don't alter it unless the plants have a negative reaction to it, I also run my EC at around 2.5 in veg using the Canna Coco nutrients.
