ph meter and clones ???

[cruseonme]

I got a hanna ph and i was wondering do i only need the 7.0 calibrating solution cause this thing has different ways to calibrate. also another question is if i take rooted clones and plant it in ocean forest soil is it ok to give light dose of superthrive? thanks

I calibrate my PPM meter and PH meter every time I flush.. Maan, I forgot , I got to do that tonight. Yes get the calibrating solution. Every time I calibrate, I'm a point or so off. (it adds up)

Depending on the meter some come with 2 calbration solutions, 7.0 and 4.0 and there is a 2 part process to calibrate the meter, this is more accurate than the one step calibration meters.
