What is the pH of the RO water before you add stuff? Why did you switch to expensive water?

 

[albewokanobe]

I dont check b4 nuets
I have ro filter in my hardware store so its free water just trying to avoid municipal water with no filtering
I will check it

Also im using phosphoric acid ph down its very powerful. Ph of 6 straight from the filter and brought to room temp.

Hey,

So your RO without salt is 6.0. Which phosphoric acid are you using, mono basic, dibssic?

Nice chart! It reminds me why I grow organically.

Albe,

If you look at that table. It speaks to acid rain. Depending on which phosphate form you are using consider this acid rain. Only to help maybe interpret the rable.

Nice chart! It reminds me why I grow organically.

I considered doing hydro at one point and did some research and it always ended up being "next grow". Honestly just don't have the time to maintain it so I just stick with soil.

Its the ro water. Having nothing in it including ph stablizers.

I did a few grows using a ro system water and haf notjjng but problems with ph fluctuating crazy within hours i was adjusting 3 times a day.

Started using tap water at 700ppm from the tap already, but never had them ph fluctuations again.

Its hard to believe but i still put the full dose of nutes on top of that initial 700ppm and never had a problem since no slimy roots, nothing tje only problem i had wad the crazy growth i had to constantly be controlling. Give tap water a try
