That article was good. I'll do some looking into it, but I'm sure you're right. When I was cutting the spring water with other bottles spring water the other grows did find. I don't grow too many plants so buying a few gallons of water a week is okay. I'm going to go see what I can find out about hardness and salt concentration. So when you say issues bc of the salts you're referring to the salt concentration being 128.6?The water seems fairly hard and may cause you issues because of the salt. I think the upper limits for greenhouse is around 30mg/l but only one way to find out for sure. Maybe you could use a more acidic mix with peat that could break the carbonates apart?
I was thinking that perhaps it was getting hit with a water softner but after reading again I am going to assume it is not.
Elevated Sodium in Irrigation Water and Crop Injury
Elevated sodium and chloride levels are being observed more frequently in private water supplies in rural areas.extension.psu.edu
That helps a lot. And that could very well be it. I never stopped using cal mag during this grow.You've got a lot of calcium and magnesium in your water. Getting the pH of your water adjusted is easy enough, but you will need to watch out for lockout due to too much calcium.
Make sure your nutrients supply calcium through a separate cal/mag product and then don't use it. Supply magnesium, when needed, with epsom salts.
This is my third grow. Everything's been done exactly the same each grow. The other 2 grows went great. Then I changed the water I use on this grow and I've had issues that look like lockout or ph issues since week 2 of flower. I'm really thinking it has to do with the ppm being high in this water and the previous water I was using was low ppm. I didnt know enough at the time to account for that. But thanks to all these helpful people, I do now. I focused on the one variable that changed and figured that would be a good place to research. If you have anything helpful to input, I'd def love to hear it. But since flushing things are looking better in there.ok why you researching your water? whats wrong with the plants that your blaming the water?
aren’t you growing with fox farm?
if so why are using the chemical ph up/down in an organic medium?
it’s not your water..
"Any of the imbalances or impurities in the water analysis above will contaminate the plant thru osmosis. All the stuff above has to filter through the plants. When a person stops using tap water they will find out how much better growing cannabis can be with clean water. Everyone's tap water is different and telling someone to use tap because they do is misleading because everybody's tap is different. Treated Tap water will never be as good as RO or Rainwater. The difference is night and day because plants use so much water daily.
I'm not sure where you got that info but there is no good rain water any more & RO water strips my plants of its nutrients and bleaches out their leaves within just a few days of using it. When using RO water in soil I believe you need to add all of micro nutrients your fertilizers don't have in them or end up with problems.Treated Tap water will never be as good as RO or Rainwater?
Thank you. This grow is almost over and I've got one more grow with fox farms stuff before I try living soil. I may just try this water again next grow but like you said make sure to adjust ph (the whole first half of the grow my ph pen was off and needed calibrated). Also I think I'm going to flush a couple times throughout. I've heard different things concerning fox farm nutes and if they need flushed.The water report looks fine with maybe the exception of chloride at 37ppm. Weed doesn't need chloride. Too much can be a problem. Doubt the water is the problem here.
Calcium and magnesium are normal and not a substitute for cal mag. I use 200ppm Ca and 75ppm Mg. Your water doesn't have anywhere near that.
Bicarbonate level is fine, but the water should be acidified to remove some and get the right pH.
