Tmusic it the nail the head. You need to get some PH down and lower it. Hydro should be 5.5-6.0 somewhere in that range. I know there is natural ways if you don't want to buy the PH down, but I can't remember. I use the PH down/up

And not trying to be rude but maybe you should ditch the videos you've been watching and guides, PH is usually the first thing covered. The book phat_head menioned, the cannabis grow bible, is tops for beginers in my opinion. It's what I started with. I'm not a big grower but what I have has turned out great.
hbbusa28 Reviewed by hbbusa28 on . Suuuuuper High pH!! Finally, my friend has his set up ready to go; all temps within range, E&F working with no leaks, timers working, etc. But he tested the pH with a liquid test kit (its all the hydro shop had in stock besides $120 testers) and it read over 8.0. We waited a couple hours for it to run through a pump cycle once or twice and measured again and it still said 8.0+. Why is the pH so high and what should he do about it? He is ready to germinate the seeds but doesn't want to put them into the system Rating: 5
