HELP!! ppm scale for canna nutes range

hey everyone, happy 4/20 today!!!

first post in this community and really hoping to find some grounding with everyone as I would like to start posting more on my current first grow & beyond! now to the questions

1. i’m using canna aqua ranga for my first dwc grow, i’m about to buy a blue labs ppm/ec pen or meter and i need to know what scale of ppm does the canna range use. 500 or 700? ec hannah? i know blue labs read both but i’m not too sure on adding nutes now

2. what’s the best bluelabs meter? the basic ph and ppm meters or the combo meters. i need some feedback possibly from owners of both ? wanting to know is the combo meter or 24/7 guardian worth it or just go basic and a tiny bit cheaper.

thanks guys, love from new zealand !!

I LOVE my new Truncheon stick. I should have bought one years ago.

that’s what i wanna hear man haha, what pH pen or meter are you running with that as i wanna know if i should just get a Truncheon and a bluelab simple pH pen.

I hate ph pens. Might as well try Blue Lab if you are going to try one.

i’ve heard ONLY good things about bluelab range. would recommend the bluelab combo meter (pH, EC or PPM and temp) as it ordering it now and it’s only got 100% good feedback. bluelabs is a company where i’m from, new zealand, and is the world renowned best hydroponic meter company apparently, also get 5 year warranty!! just wanting to know from an expert here do the combo meters run on ppm700 scale or 500?

You choose which scale you want to use, it can read EC, PPM 500, PPM 700 and CF - EC is universal.
