RO water kills my plants.

Sooner then later I am going to city management and see if they can test a sample of this water for me. Hopefully they can tell me if there are toxins.
 
You guys crack me the fuck up...worrying about whether your water is fucking up your grow...lmao..it aint hardly ever the water unless you give it too much. Most water, tap, rain, ditch is fine...any water is great except for RO which is shitty for weed...ph is wrong and no buffers no nutes..all that fiddling around with your ph and nutrients, up, down, temp changes, etc, etc...your plants would do just great if you left them the fuck alone, fed them occasionally and watered them whenever they really needed it. You guys are making this shit harder than it ought to be....bet you own "expensive glass" too....

I use RO water.
I raise the ph first with protekt (takes ph to 10.0)
Then add cal mag which drops it back down to wherever.
Next comes espom salt and micros.
Finally macros.
Ph is usually looow like 4.9.
So i add protekt till its bak up to 6.5-6.9.
Plants are healthy. Stems are thick.
RO water has to be "tamed" first with buffers or yu'll experience crazy ph swings.

My first thought thou was wat kind of RO system yu using? Some systems add sodium.. Salts make plants shrivel for obvious osmosis reasons. Perhaps roots are being raped by it?

FWIW my RO water starts at ph 8-9.

Did you ever figure this out? I have the same exact issue. Installed a new Reverse Osmosis System connected to the kitchen sink. PPM is 11. PH I set to 6.0-6.5. Running the grow just like I have for years, but now using this Sink RO system, when I water the plants start dying. WTF ?

I just checked for you. Have you tried feeding them?

A wise poster said a few years ago to add H2O2 to RO water as most of the O isn't present anymore. It will help them germ I guess. Never tried it, I use tap water. Just fun replying to old posts.

Wow just wow. That would mean everyone would be producing straight hydrogen. Ppls kitchen sinks would be exploding left and right. Is that why ppls weed sparks too? I mean you've been watering with a straight explosive if the oxygen is all gone or mostly stripped.

If you've been growing for years then why did you even switch to RO water?

You're not doing something right here's some of mine watered with ro water ph'd to 6.5 and feed every so often and hit with recharge.

If the oxygen's gone it's no longer water.

The broscience is thick in this thread.

ive recently switched to ro because its something new to try for me and more control of whats going in. sometimes the reg ol routine can get dull. always nice to try some new things and stay relevant in an ever changing industry. plus keeps the noodle tickin

I'd bet a lot of people confuse an RO system with a water softening system and then come up with a lot of different explanations as to why their plants suddenly started doing poorly or dying right after they got that new system installed to treat that hard water.
