Are my ph levels to high 7.6 bought spring water at the store tested it at 7.6 , plants are at two weeks old nice and green beside two that look like they have nutrient lockout first time feeding at these level figured it would be better then my tap water that was testing at 6.5 iwas letting it sit three day bubbling with a air stone and still looks like its burning plants with no nutes will the 7.6 spring water be better then my tap at 6.5 thats burning my plants whats wrong with my 6.5 tap water.

In soil the pH needs to be between 6.0 and 6.5

In hydro between 5.5 and 5.8

Optimize your pH to 6.0-6.3 for soil and 5.8-6.2 for hydroponics. By staying in this range, you permit your plants to uptake non-toxic quantities of macro and micronutrients. It'd also be beneficial to post images of your plants and provide your grow room specifications to omit or mitigate any additional problems that are contributing to your plants' scorched leaves. I'd recommend pH'ing your water and feed your plants with a CalMag supplement to start off.

For hydro, the sweet spot is 5.8

That said, you will have drift. Setting it to 5.6 and letting it drift to 6.0 before bumping it back to 5.6 is optimal.

That's a nice tap water pH. If the EC/ppm of your tap water is also low (which is likely considering the pH) - consider yourself one of the lucky ones and use it. The only other thing I would check (if you are in the US) is if your water utility supplier lists chloramine instead of the more commonly used chlorine. This will be listed in the water quality report under contaminants/byproducts of microbe control and should be available online for you.


Edit to add: Doesn't hurt to ask, your water supply isn't on a water softener system is it?
