Hi,
I've got a pH problem that I cannot solve - is there anybody here willing to help?
I was using 2 days old tap water in the beginning, but my pH once balanced would grow by 1 in half a day.
I had decided to change to demineralised water, but when I was filling my res for the first time I have lowered pH too much and added some tap water to bring it back to 5.8
I did the water change at noon and at midnight it was 7!
I changed water again, this time I managed to balance it to 5,8 after adding nutes.
guess what?
I just checked the pH and it was 6,9 now after only 9 hours!!!
I am using GRODAN rockwool as a medium, GHE TOTAL GRO, GHE BIO ROOTS, and GHE pH DOWN buffer.
I brushed the res before changing water,
oh - I germinated plants in rockwool using tap water - do you think that this could be influencing the pH until now?
Please help - I am planning to be leaving for 3-4 days several times soon - I have to do something about it!
