Hey guys so I've purchased an EC and pH pen online and I'm just looking for some advice on how to read it. There's no decimal and I think it reads in us/cm. I've looked online and it says to divide the reading by 100 and that will give me the reading in ms/cm. Is this correct ? Also what are the optimal EC levels and PH levels for Coco 🤘🏽💚
