hi there, am growing in canna coco, using ro water.
Am using botanicare cal mag and flora nova grow. Plants have been vegging for two months. Have looked pretty good until now.
I feed ph 5.8 - 6.1 , 900 ppm x 500 scale. 10 percent run off. About every two days. Plants are under 1000w ushio metal halides with adjust a wing reflectors. Sealed room, 800 ppm Co2.
What is going on with my leaves :(
Only a couple are doing the green twisted thing, but they all are doing the leaf burning. Some more so than others.
That chart is for soil (dirt). You need to use the one for hydro for coco!Check out this picture.
At 5.8-6.1 your plant is only receiving some of the stuff it needs. I would bump the pH to 6.4-6.5 also add some "iron & zinc" to your water and you'll see the difference. I had this same problem about a month ago
Thank you! It's a Puerto Rican vejigante.@Seamaiden ...As usual great diagnosis; like your new pic (new to me ).
I also did not use ro before either, am on a well and had it tested and they said there was sodium in it, so decided to put an ro in. The water has been fine, but decided to play it safe. I have a water softener and think it's been leaching salt into my well.Ya but as some of the people said they never have and have never had issues, I've grown here for 5 years and have done really well until I switched to coco from pro mix this round.

To the OP, I have had too many issues with ostensibly calibrated meters to not make that one of my first questions if it just doesn't seem right.
It's happening to me right now with our tap water in our new home. I'm getting a reading of 1ppm NH3/NH4+/- (ammonia/ammonium) straight out of the tap using my API aquarium test kit. That ain't right, EPA only allows something like .3 or .34ppm. (Reminds me, I need to call the water company because they only show NO3 as even being tested, not NO2 or NH3.) So I first question my testing methods, then the kit, and if all are shown to be satisfactorily reliable, then I'm going with the results.
If your run-off is coming out 400ppm higher than input, I think you're zeroing in on your issue.Ph meters seem find, double checked with a new handheld.
Did a slurry test with ro water that I had to slightly adjust to 7 ph. It said 5.7, on 2 meters. And that was the worst looking plant, they all are getting worse, stopped growing and are pretty much just eating their leaves. I checked the run off ppm, watered in with 1100, came out 1300 ppm x 500.
Am going to truck city water to my house and stop using the ro. Having a tough time watching them get worse day after day.
Uh huh. While it's never happened to me, this does stick out.I also did not use ro before either, am on a well and had it tested and they said there was sodium in it, so decided to put an ro in. The water has been fine, but decided to play it safe. I have a water softener and think it's been leaching salt into my well.
