Can you give me a name of a Ph meter that you know of that is reasonably priced and accurate
I have been using a HM Digital pH Meter - Perfect Gardens reliably to measure and adjust the pH of my nutrients with.

Is it necessary to have all three calibration solutions or can I buy just the 7.0 solution with the tester
The HM Digital pH Meter - Perfect Gardens only requires pH 7.0 calibration solution.

How often should I ph the runoff of the soil
Anytime you begin seeing any leaf damage or suspect a pH imbalance you can easily verify your mediums conditions with a soil runoff pH test.

Hey kingjohn c I'm a new grower with alot of questions. I read up on the internet every day about grow techniques and pertainant info. Would you be willing to be my teacher or one willing to answer questions when asked. I got a good base to start from but being a novice grower can bequite overwhelming

From the posts that I've seen and read you seem to be knowledgeable about growing and I need a good teacher to take advice from. Plz accept my request strictly for information purposes
You are welcome to ask me any questions that you have, I will try to answer you as best I am able to. I have several Grow Journal and Reviews in progress that you may also ask me questions if your question does not directly address pH adjustments.

I added you to my friends list. Don't worry I won't be sending dumb ass messages that don't pertain to growing. I think it's great that people out there will offer Help and advice to a complete stranger. Till next time. Thank you

Great thread! This just about makes it to easy.
To be sure I understand, add nutes to water. Rest, check PH and use up/dwn to neutral 7 then swap water in resivore. Repeet for life of plant.
How often should i repeet the cycle?

The pH that your nutrient solution is adjusted to is changed depending on the medium you are using to grow your cannabis plants in. Add nutrients to water and mix, test the pH of your nutrient solution, use pH up to raise the pH of your nutrient solution or pH down to lower the pH of your nutrient solution, test the pH of your nutrient solution and apply to your plants. Nutrient reservoirs for Aeroponic or Hydroponic systems are also adjusted as needed.
You want 70°-90° Fahrenheit and 50%-70% humidity for vegetative growth and 30%-50% humidity for flower.
You want pH 5.8 for hydroponic and soiless (peat moss and coco coir) and pH 6.5 for soil.

I watered my soil with ph'd water of 6.6, but the runoff is between 7 and 7.5 (weird I know), so I reckon I should give the next watering with a ph of 6.0 right? The runoff will be less then, hopefully with a ph of 6.5-6.8?
Thanks.
My plant is also yellowing and twisting like a mofo, I am sure it is because of the ph lockout.
It is in late seedling stage, can I flush it?

Yea, bringing this back. New hydro grower here and just got a waterfarm. I've had huge PH swings during germination from just plain water. Drove me nuts and GH, of course, said my water quality is causing the problem. I read a grow journal here and the guy had a waterfarm and had the same problems I had. Long story short...I googled "PH issues with hydroton" and was shocked at all problems guys have with PH rising from hydroton. Waterfarms use a lot of hydroton in a 2-gallon res hence the dramatic increases in PH. An expert claimed that rinsing hydroton in a 2:1 water and vinegar solution helped stabilize it. I simply rinsed it in water until there was no residue left; a newb mistake. All that said I'm 2-weeks into veg and my PH increases about 1-point in about 12-hrs. My TDS is about 450 PPM. I'm adding 1-1/2 mil of PH down twice per day to keep my PH around 5.8. Is adding this much acid to my res going to hurt my girl? She looks fine and growth is consistent.

I got one of those, what a piece of shit instrument !! Reads 7 always !! What good is that ?? It's 8 yrs. old, but brand new, don't know why I keep hanging on to it, like all of a sudden this piece of crap is gonna start working !!. Maybe I just didn't know how to use it. but I highly dought that !!

I would flush your plant until the runoff is pH 6.5 for soil, pH 5.8 for peat moss and coco coir.
