super high water pH

Sensigrower · #1 (**permalink**) 04-29-2007, 02:22 AM

I have 4 DP master kush plants and everything was fine until about 4 days ago when I noticed 1 of them was showing signs on nitrogen deficiency. I checked the pH of the water that I had been giving them and the reading came back as 9. I know this is a bad thing. 2 other plants are now also showing the same symptoms. I have grown before about 3 years ago when I used bottled water that had a pH of 6.5 or thereabouts. However, I can't seem to find that brand of bottled water anywhere now and the only brands I find all have pH over 7. Please advice.

buy phosphoric acid type "PH Down" from hydroponics shops or "ebay" sells it aswell

you need to flush your plant if the PH reading is out of optimum range 6.5-6.8
flush with PH corrected water 3 time the volume of the pots
EG: 1 gal pot = 3 gal. flush
add 1/4 strength nutes to the last gallon of the flush

Thanks for your reply Ganja Guerrilla.

Thats what I plan to do but the thing is where or how can I get water with a pH of 6.5-6.8 ?

your PH is high you add "PH down" to your water to get it in the 6.5-6.8 range

Is that the same stuff tropical fishkeepers use ?

any kind of acid changes the PH however the type I suggeted to you is beneficial for the plant your growing it wants lots of Phosphorus
