Ph Way to HIGH for 10 days, Problems Coming?

I just bought a new ph meter, worked for 2 weeks, Changed my res and put my plants into flowering. That day is when the ph meter stoped working. So my plants have been flowering for 11 days and have been recieving floods 3 times a day with a ph of 9 maybe higher. I used the Gen Hydro ph test kit, vile and drops it was blue. My clone box has been going for over 2 weeks, All finally have rooted, Fairly well. My plants look Great, No signs of any problems. Does anyone know if I'm in for surprises and heartache from this problem. Or if I correct it and keep it correct will they power through this? Thanks in advance to all replys

i would flush, renute and keep stable ph... kids will be fine

What is the best way to flush rockwool?

just run ph balanced water and do 3 flood and drain cycles then change res with nutes

Nice vertical, I will be experimenting with that in a month. I would love to see the blueprints on yours. I might "BORROW" some of your ideas , LOL, Do you have everything dialed in? Any complaints or things that are a must have

thanks man i appreciate it... i went over a few things on the last page of my journal but for the most part i love it... it takes a lot of time to flush and clean stuff out but the added hassle is worth it for what you get in return. i havent used all of the sites yet so i will have a better idea when they all get rolling this next go around. i think the only major problem is i want it bigger haha i would love to do like a 150 site with 4 1000s...that would be sick..
