Popular PH recommendations VS PH in practise

I was just trying to figure out the right PH for my next grow & thought I must raise this question within the RIU community.
Im was growing in hydroponics maintaining the PH at 6.2 & my Blueberrys looked incredibly green & healthy with not a defect in sight, despite popular teachings stating to aim PH for 5.8 in hydroponics. So how can it be that the increased PH proved successful? I just cant understand it, can it be that certain strains prefer a slightly lower or higher PH just the way plants cope with PPM?

I wish I had asked Al B Fuct when I had the chance.

Al B Fuct is back, btw. He has a new thread just for you too.

I've done a lot of research on pH Control and I 'd like to offer some advice and my opinion.
NEW growers worry about it too too much, and the biggest mistake they make is trying for a perfect contstant same pH.
You will do better, to just try to keep it between 5.6 and 6.8 without changing it often. Plants eat more nitrogen at 5.7 to 5.9 than at 6.7 to 6.9. But they eat more iron and magnisum at 6.5 to 6.8. You need a flucuating pH level for your plants to absorb different nutes at different levels.
When you get your water, add nutes and pH test it, no matter what the results, if it is between 5.6 and 6.4, leave it alone or only adjsut it by .1 to .2 down.
DO NOT PLAY the pH Game.
do NOT ride the pH Roller Coaster.

Drastic or FAST adjustments really mess up the entire system.
Adjsut gradually, and slowly.

Hey there Roseman Ive seen your avatar all over RIU. Al was back but has returned to his work this I raised this question afterwards.
I was told to keep my Blueberrys at 6.2 PH at all times (hydro). I was told that PHing to give your plants the neccasssary nutrients should not be done & only to stay at one PH range.
Oh man I really need Al or Heath Robinson or anyone who knows in practise to answer this question.

Thanks for your input Roseman.

I hate to put words in anyones mouth, but if Al were here i'm sure he would tell you. "if it ain't broke, don't break it"
If you're having success with a certain PH, there is no harm is keeping things the way they are. Every plant has its own ideal circumstances. So long as they're happy @ 6.2, 6.2 sounds like a good place to be.

Having said that, as roseman stated, PH drift is a good thing.
Personally I change my Ebb and flow Reservoirs every week, and during that time my PH will drift from 5.5 to usually about 6.3, I find this gives me the happiest plants.

Heres a chart that could be useful as a reference.


I'm sure you know this by now, but there are a thousand different ways to grow marijuana the "right way". If you've found something that is working for you, by all means keep it up. If you're having continuous success, anyone who tells you that you're doing it wrong has got a closed mind and doesn't have your best interest at heart.


In any event, best of luck and happy growing.

Ive seen many PH charts all showing a slightly different ideal range, but Im going to take your advice & do what works for my plants.

Thank you.
