Re: is my water ok ok to use?

Hey Kush Killer I appreciate you posting all that info and many members may be able to decipher it but I usually try to grow first and then use additives if needed.
Great question +Rep
 
Re: is my water ok ok to use?

I'm certainly no water expert...and to make matters worse I'm a soil grower, but I'll throw my 2 cents in until someone can chime in with a better answer.

Obviously the pH is high... It would be okay for me, because a properly constructed soil mix buffers pH, but you'll need to adjust that for hydro.

Also seems to be moderately hard, so no need for CalMag.

Total Alkalinity is borderline...ideally you would like to be under 60 ppm (if memory serves) looks like your water ranges between 50-148. This is the most important number on the whole report in my book. It's the total concentration of bases in the water. If the TA is too high you can correct pH but still have problems.

I would probably recommend you dilute with RO water to keep your TA In the acceptable range (and need to add less pH down).

Just my thoughts... :Namaste:
 
Re: is my water ok ok to use?

I'm w/ Fratdog.....cut 50/50 w/ RO and you may not need any cal/mag supplement then. If you don't have a RO filter now, you may want to do a test grow to see how the genectics and fertilizer you choose works with what you have. Just understand you may have to do something if you have problems (get an RO setup)
 
Thanksfor replies guys, I have another thred in problems,pest,diseases, in reguards to this issue as well. I think next res. Change ill run 50\50 ro\tap... I'm haing very slow growth an mayb someone could go look at my other thread check out the pic and reply?
 
Your water has a lot of minerals that RO water users pay money for, so that's a plus. Not sure about the alkalinity issue, so will defer to others. As to ph down, save a lot of money and buy distilled white vinegar. I pay about $1.50 a quart. My tap water is 7.8, and I run at 5.8 and less than a half tsp per gallon for ph control.
