    Hi everyone!still having the ph dropping in my Rez,been trying to figure this out since I started growing in my BB,started week 6 of flower,plants look great,lots of nice buds!But why !Using well water,ppm50-60,using chiller set at 66,future harvest nutes 1/2 strength,ppm 750,adjust ph to 6.1.Flushed Rez 3 time’s with ph’ed h20,checked this morning ph down around 5.5!wtf!and yes blue lab ph control calibrated properly!

    If in fact your ph reading is calibrated properly and your plants are not showing signs of calcium deficiency then I question your calibration method.

    It’s unnatural for your ph to go down if you did nothing. Whatever you do, never mix ph up and ph down in the same soup. I would disconnect your blue lab first and ignore it. Listen to your plants. If it truly was below 6.1 your plants will quickly let you know. You’ll see brown crispy dead leaves. Did I mention never mix ph up and ph down in the same soup?

    I use future harvest nutes and I Always have to add P.H. up the first few days after fresh nutes. Then it levels off towards the end of the week. I use test strips and a pen to confirm P.H. I adjust it manually. I know this isn't normal and I can't explain it. I think it's the future harvest nutes they are very acidic and the more the plants drink the more the drop in P.H. Personally once I run out of future harvest nutes i'll be switching the P.H. is very unstable using these nutes, I'll be switching to something simpler. Why Have 10 different bottles to mix up when you could have just one.

    I think in theory why pay for elements of a nutrient system you don’t need for different stages of a grow and it makes the nutes last longer? Not sure. It’s been a long time since I used them. I’m about convenience. I’ve gone to a 2 part nutrient system that automatically controls the pH, regardless of the water source’s pH, so I never have to test it. It makes a blue lab virtually obsolete.

    ok McLovin, What nuts do you use? I'm looking for Hydro Autoflowers food. If you can have an opione, I do not know why auto would make a difference but interested in finding out.
    Thanks

    My plan is to switch to mantis once I run out of future harvest. I've heard nothing but great things about it, and one part solution that's P.h. stable would be so much simpler.

    I use Advanced Nutrients. Their entire line is now pH balanced. I believe they were the first to market with this technology and now I’m seeing others. Originally AN were the nutrients provided with these boxes before FH. I think they changed over because it was a US product and wanted to keep everything Canadian. No one has officially said the reason. The pH technology didn’t exist then.

    Nothing but positive reviews have been posted here on the forum about Mantis. It doesn’t appear to be sold in the US.

    So you never drain the rez, you just add as needed the entire grow?
