PH Question

[panta]

i got a ebb and flow table plants in perlite,the perlite seems to be raising the ph a bit every day,i set it at 5.2-5.3 i try to keep it as close to 5.8 but it gets to 6.0-6.3,is that alot of oscilating,do i need to adjust it every day

i grow in soil, but i have tap water with a very high pH. when i treat it and water the plants, it seems to rise over a few days.

get ph up and ph down

or an ro unit, preferably a 5 stage DI. OR could use things like dried peat moss to lower the ph.

There is no problem with it shifting in that range. The worst thing you can do is chase it around trying to keep it at 5.8.
