RO water kills my plants.

That means everything would go backwards. Holy shit ro water is the key to reversing aging lmao.

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.

i mean if you dont add something back to ro water itll strip nutrients faster. i think thats most ppls issue. theyre not accounting for several factors. but ppl are odd creatures most seem resistant to learn or think.

Damn and here I wanted to get solar on the new house when I can hook ro to a reactor and run my town.

I was asking OP if they found out what the issue was with the RO system. Not you pretentious all-knowing cannafags.

Still there Truckn?

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 ?

Lol.........this thread is 9 years old.
I doubt the OP will respond........he/she hasn't been around for over a year.

It sometimes takes a decade for us cannafags to figure things out though. So maybe in a year or two he'll update us.

Lol damn man. Sounds like you just like him who has been around in forever don't know what you're doing. You gave no details other than you used ro water. Several factors can influence your end outcome. Are you adding anything back to the water? What are you feeding at. What medium are you using? Let's see what your plants look like perhaps. We cannafags need a few more details to know what's going on with your plants. So pull whatever got stuck in your ass out and let us know where the bad water touched you or shut up and carry on and figure the shit out on your own.

Last December I installed a new reverse osmosis system and ran my hard tap water through it. Out of the tap it's ppm is around 640, and its pH is higher than the recommended for growing. This system managed to take the water down to 30 ppm and 6 pH. The problem comes when using it on my plants, lately I tried it in my cloner and it made them all shrivel up. So next time I took a batch of clones I used RO water from the store and had no problems with it. And when it comes to my bigger plants it's the same issue it makes my plants shrivel up and die.

So my question is what contaminate could possibly be entering the reservoir during it's filtration process that is causing all this duress.

Maybe try leaving the water uncovered for a day see if somehow chlorine getting through check with manufacturer see what their filters remove and don't remove, there is different standards that's so weird though because I use my own RO and never have issues even when straight water

Chlorine won't kill your plant for one. Two Chlorine will be represented by a ppm number of 100-150ppm. Also still talking to basically a dead guy.

Sounds like you don't know what you are doing with ro and can't give details as outlined.

Technically yes chlorine can kill your plant in high enough levels (yes should never happen with levels in any standard city water supply or any water supply but technically speaking it can lol) also didn't realize it was like 9 years old. Yes there is different filter levels for RO and companies have different amounts of things they take out or guarantee to remove or reduce to certain levels. My question to you is why would plain RO kill clones? I'm asking as I'm going to try to clone next grow and want to be prepared for any issues, my RO ppm is 0-5 and I havent had any issues yet from seedlings to flower.

Ladies, and gentlemen, of the thread, I bring you the solution to this problem.
I was having the same issues as the OP, the RO water I had been using for years suddenly started killing my plants.
I replaced all of the RO filters, nothing changed.
Finally, by chance, while reading another thread, somebody posted the answer to my prayers.

Add it to your water before adding the nutes and you’re golden.
Thanks a million @CaliWorthington

i use ro on all my cuts and they root in 5-10 days.
are you watering with the ro straight from the unit at like 48°? thatll sure kill your plants fast
here jump in the hottub time machine with us cannafags and well go back to 2012 and ask truckn
instead of 'well known member' i want my title to say 'cannafag'

oh no more bottles....
cant we just add some calmag and ph the solution when your done???? why add more bottles and more junk
crazy what people will buy sometimes

It wouldn't. RO water is just pure water with all minerals and contaminates removed.

That's what I thought.

don't bother with calmag supplements or any other product
get a soft water line of nutrient

i use 100% RO water/air conditionner condensate water with dutch pro RO/SO nutrient line

calmag is unsuited to stabilize RO
it do not even buffer the ph of the water properly, just bring the missing calcium, unbalancing the npk ratio

hard water formulas are designed to work with water buffered by calcium carbonate, the acid in the nutrient will react with the calcium carbonate and make it avalaible for the plant
its totally unsuited to RO water or very soft water, because it will acidify way too much your solution, forcing to use ph up

some manufacturers make soft water/ro formulations, ghe .. ionic.. dutchpro(my fav) and many others
the key is to find fresh batch and not old bottles with precipitate at the bottom


they are always fresh here

thank me later

RO filters can also screw up the waters EC and that's why the buffer (pH Osmosis Stabilizer) is needed.
I tried fixing the problem using only pH solution before and it did not end well.
Without the buffer, the nutes will always tank the pH levels.

RO filtered water shouldn't have any EC (at least if the system is functioning properly). That's why you can't "fix" the pH of RO water... there's nothing in it to fix or adjust ionically. Same holds true for distilled water (which definitely shouldn't have any EC).
