Ideal PH for soil

[funkervogt]

Sorry for the post title, I screwed that up. I'm looking for ideal *water* Ph.

I've seen this answered in several different places with different answers, but none that are definitive.

What is the ideal water PH? Does the stage of growth matter? If water PH should be adjusted, how should this be stepped up/down over time?

Thanks and best,
FV

ph water right before you water plants....water ph is best at 6.2-6.6

i run 6.2 ish also

 

[driska]

have 6.5-7.3 Ph with no problem

 

[Rjstoner]

this is what mine look like at 6.2 ph





pictures taken this morning
and here is a chart for what a plant intakes at different ph's

I never test ph... My ladies look great... I have been farming for 15 years...

Ya I run 6.5-7.5 and no R.O hear.. soil is forgiving unlike hydro. You should be ok.

i agree with nugmaster, i never PH my water. roots have the ability to correct pH themselves. unless the media is made up of 100% peat, there is no need to worry over water pH.

i dissagree about no checking ph. we have water PH 8-8.5 so we must check ph every time

i have lived in many different places... with a variety of water qualities... all i do is let my water sit out for 24 w/ out a lid... then water away... no need to stress over ph... if your ladies don't look good... it more then likely is due to some other factor...not your ph levels...

By RjStoners ph chart and the one I have which varies slightly from his, the macro-nutrients like N-P-K and Ca & Mg uptake is better with higher PH-like 6.5-7.0, but for the micro-nutrients, a slighly lower PH 6.2-6.5 is better for greater uptake of those nutes, like iron and manganese.

Ya ur both right, ur ph plays a huge role if u have a soil that dosent drain properly, but if u have good soil u can go up to 9.0 ph water with no problems.. at least that's what I have seen, but if ur ph is higher then 8.0 in your water u have more minerals then u want... lows and the depot sell one sink R.O systems for under $200.... maybe for u to drink out of and ur girls....

man i wish i new how to us this computer better. for the luv of god ph has major impact. i use cyco neuts.pure tap water no filter ph 9 eeck half strength feedn brings to 6.5 to 6.3.only ph untouchd water neuts lower it so be careful.had low ph got tiny buds fix ph and my tops compare to pop can and plant is only 4ft or less.good harvest for me is 4to5.75 oz dried

PH affects how much available nutrient uptake will take place, along with the proper amount of water & food, Co2, temperature and light.

i try to keep my ph around 6.0 to 6.7 keeps them nice and healthy.
