yes that is similar to the ebb and flow systems that I have.
Sprayers at each grow hole
Using Hydroton
FLORANOVA BLOOM for the nutes, 17 gallon reservoirs keeping the ppm at about 1850 at this stage.
I don't know if the water is chlorinated, I am on a community well and up until two months ago I have never had this problem. Ive always used the same nutes and process so I cant think of anything to change to make this stop. The only time light gets to the nutrient water is when I'm checking the PH and PPM during their light cycle, which again I have always done this. Should I take a water sample somewhere and see if there is anything off with the water? Tap pH is right at 7.0 and PPM is 100.
Hey janie, so you're not a boy named Sue? hehe
What I was trying to determine with all the questions is if you were doing anything yourself that might be causing the pH fluctuations.
I don't see anything, so that leaves exactly what the other person said. Something has become so strong in your system that it's altering the pH.
I would advise you to flush your system out with fresh, no nutrient water and then fill it with only water for 3 days.
Take pH readings every 10 hours if you can and see if it's climbing again.
After you do this, let us know what happens.
If that stops the pH climb, then we'll look at how you mix and add your nutrients. If you're mixing them right in the reservoir, that's a no-no.
You should always mix them separately in a two gallon sized opaque container and then add to the reservoir after that.
Let's see what a 3 day flush of your system does.
If you're on a shared well, I seriously doubt that anyone has put chlorine in it unless they were doing a decontamination on it and they should contact everyone when that is done.
Good luck janie. We'll figure this out.
Hey, an ebb and flow doesn't use sprayers unless it's modified to do so. Do you use sprayers with your ebb and flow? The ebb and flow fills from the bottom up and overflows into a drain line. Usually, there is no other delivery system for the water. The one in the picture I attached is a Modified NFT system.
Dr. Howard Resh has a book named "Hydroponic Food Production". It's considered the "Bible" of Hydro. I would strongly suggest that you buy one and read it. It's worth it's weight in gold.
