PH Drama

Hey, my tap water ph is 7,7 it really takes every day a decent amount of ph down to keep my range optimal

i have a 5 gallon dwc setup

my question is should i buy more ph down or better buy distilled water which i again need cal-mag ...

or are there good ways to push my ph down with organics like baking soda or other methods i seen on internet not the chemical sold products.

what would you guys do in my position ?


PS : Merry Christmas to all

i dont know because with my current usage i end up with 0,5 l bottle for 1 grow if not even more .... i thought the 0,5 l bottle will last me more then 1 grow since all on videos warn how strong that ph down or up are ... i basically need everyday 35 - 40 ml to get my ph in range

got 18 - 20 liters of water in my rez

sry for liters im a european.

pH rise usually means the plants are using the nutrients.Are you measuring your EC or just using measuring spoons? If it's just spoons you need an EC/PPM meter and now.

You could use a stronger acid as pH down.

Or mix the tap water and the RO, so you won't need as much of the RO, and you won't need the calmag because you added tap...

While I agree with only using RO water, I have to wonder if you are using rockwool?
I've seen where growers who don't soak the rockwool for a day or so before using, it caused PH
problems simular to what you are experiencing.
Peace

no i don't use rockwool, going directly in hydroton and water it with the same rez. water from the top 2 times a day / morning and evening

eh what do you mean by stronger acids aren't the ph down or up the strongest in it's own way ?

no i dont have a ppm meter i ordered one but it will take some more time since it's from a external country.


well, ya RO seems to be better but it's quite expensive and it's not forever u have to rebuy the filter tubes if i understood the system therefore isn't it better to just buy distilled water ?

At least use RO and a tapwater mix.

Dude, you can buy a decent 3 stage RO filter for 50 bucks on amazon.
Personally I bought the 5 stage one for $150, cause it came with a faucet, a 4gal holding tank and an xtra set of filters included. Money well spent.
It makes a big difference to the water too.

not sure where you are at but i buy my RO from walmart for 37 cents a gallon. i only use 10 gallons per week so it's not a big expense for me.

can you buy distilled or RO nearby? then you don't have to worry about the expense of buying your own RO system

Figure out the ppm of your tap before you go buying shit. My tap comes out @ 50ppm .5 conversion.

Strips are accurate unless moisture got on them. Ph and tds/ec are really important in hydro.

Sounds like your water is acting like it can't buffer properly. This is usually because the water is pure.
