if the ph of the water is 6.5 does that mean when you water you make the soil have a ph of 6.5? should you water everytime with the water adjusted to the proper ph?
u want soil to be 6.8-7.1 so water it with 7.0-7.2...i water till i get just a lil bit of run off from the holes at the bottom of the pot and then ph test it with a ph meter..i found out that whatever my ph was goin in it would always b lower after it goes through the soil and drained out

I have a quick question about my aeroponic set up.. I started the pH in my reservoir at 5.5. It moves up during the day to around 7.5. I switch a gallon of 7.5 water out with 5.5 but by the end of every day its back up to 7.5 or higher! Please help. This is not where I want my pH to be and I need some assistance. Can someone please tell me how to keep my 6 gallons of hydro water to stay at pH 5.8-6.0 without having to adjust it twice a day?

if youve add nutrients to your water , can you still use ph up or ph down or is that gonna mess things up?
Bump up for an answer! I want to know this too.

I got Fox Farms ferts, and it says to feed nutes with every other watering. So do I (we) pH test after we add the nutes but prior to feeding the MJ? I bought pH UP and pH Down. I wish I had known about the baking soda and vinegar thing before shelling out 20 bucks for both combined
.

Thanks :leaf:

pH up and pH down work great.... but use small amounts. The bottles I bought will last me about 10 years or so...lol
good luck

I'm pretty new to this but from what I've read, you want to test the ph of what you're pouring into your plants. So I take that to mean that if I'm feeding, I mix the nutes w/ the water, test the ph and adjust w/ ph+/- before feeding. If I'm not feeding, I test the water's ph and adjust with ph+/- before watering.

this question was ask earlier but nobody gave it a DIRECT answer.

IF the plant read 5.5 and i need to raise it up to 6.5 .. another 1.0 PH UP. do we need to make something that'll give me 1.0+PH and add it into the plant or does something as strong as 7.2PH of water pour into the plant will raise it up exactly at 7.2 ph??

is there any amount of time you should wait between the time you add the ph up or down, and when you check the ph again. The PH up/down doesn't need any time to set in or whatever?

It should be noted that using organics (vingear and baking soda) in hydroponics you are increasing the chances for algae growth. Also not all PH + and PH - are equal, some are made with organics others acid based.

Good info in this thread. I think someone asked this already, but I didn't catch an answer. If you water with correct PH but the soil PH is still high or low, how do you correct the soil? Is it just a matter of watering again? And should you wait until the plant needs watering again, or do it right away? I'm always paranoid about overwatering because I know that's a major noob mistake.

one more thing what is the most important? the water ph level or the soil ph? you bring the Ph level of the water to a good value to put the ph level of the soil in a good value? thats it? thanks
