RO nute reservoir ph

As if!

Active Member
I just setup an ro filter and mixed a batch of nutes this am. I adjusted ph to 6.0. 5 hours later and its climbed back to ~6.5.

Coco grow, gh products(trio, si, kool bloom, diamond nectar) and hydroguard 2ml/gal. I also add great white mycorrhizae and some aloe flakes.

I set this up for an auto watering solution so i dont have to ph every watering....what am i missing?

Kill great white and the aloe, and nectar

Start simple, dont over think it
ok. Thats what ive been feeding them since seed. Im about to stop nectar anyways since one is 7 weeks into flower and the other

Si, calmag, micro, gro, bloom, kool bloom, diamond nectar, hydroguard, sometimes great white mycorrhizae and some aloe flakes

What order are u mixing?
taking those out will stop my ph from rising Or slow it? Thats what im trying to figure out, although i welcome the other help too, thanks. Im setting up an auto watering system but cant keep the ph in the reservoir stable.

i am also trying tonget rid of all the salt buildup as pointed out recently to me. While we are here, do you think this another 3/4 weeks? Ive never used coco and. Dont know when to flush

hahah, sorry dude im ripped

With RO water and GH, add and mix in the following order:

Armor Si (this is supposed to be first)
Calimagic (with ro water you need this)
Micro (This is before the grow and bloom)
Grow
Bloom

Now that is how they are supposed to be added and how I always did it with RO H2O but I did have an issue with TAP water, adding the Si first, for some reason when I would add the grow a bunch of shit would precipitate out. This only happened if I added the Si first, if I waited and added it last it wasn't an issue.

If you put a small mag drive pump in the res and run tubing up to create a waterfall you can get your DO without as much pH drift. Still, it can take several hours for the pH of the mix to stabilize, I hate when I have to mix up a batch right before use.

precipitate out? Meaning not disolved in the water? I have shit collecting a bit in the bottom thats red. I feel like it comes from micro. Is that normal?

Yes, like white stuff that if allowed would settle to the bottom.


Define this shit? Doesn't sound normal at all.
This is when i used dehumidifier water and some tap. I just switched to ro yesterday.

it would be like flakes of red along the bottom. Or a callection of red particles that would look like dirt(not a ton but noticeable

definitely not normal but I dunno what it is exactly. lol
So are All nutes completely disolved in your reservoir at all times?
Im going to get a 160gph(that enough?)mag pump for a 15gal bucket and try your waterfall

Yes, this is how it should be, fully dissolved. Any solids would not be available for uptake and are likely the byproduct of a chemical reaction between the various compounds in the water. If you take a sample and anything settles out after sitting still then you have a "precipitate" that was suspended in the water.

hi ren.
does this work for the water fountain you described? I put a t on my out flowing pump(400 gph) and re route the water back in.....tank is 10 gallons as you can see on the inside......

can i run the water down the side of the can so its not so loud? Or do i want that disturbance?

thanks much
