    The only essential imo is a ph meter as long as that's in check ur plants will take up what nutes u have and if its not enough they will let you know. But again that's all in experience I just think people obsess a little too much over it all and end up causing more problems than they originally had.

    I use a budding supplement that pushes the ph below 5. So I will use about 3 Tbs of phUp to get it to 5.5 or thereabouts.

    A ph meter is essential for this very reason.

    As far as TDS or EC, if you have a mix down pat, you should be able to gauge what your TDS is. A meter is VERY handy but with TDS there are 3 different scales, so use the appropriate multiplier.

    EC is the same no matter where you go.

    I hope this helps.

    Hemp I have order both a PH and EC pen, I was told that the EC pen was far more accurate since there are 3 different conversions from EC to TDS. I'm new so hopefully I made the right choice ?

    TDS or EC really doesn't matter as it is a relative measurement that you will learn to use to determine how much nutrient you are using. I don't think the accuracy difference is enough to be that important because even in young plants up to 50ppm inaccuracy isn't going to have a negative affect on the plants.

    Both numbers are just reference points so that you can say that the last time you watered with nute solution, you had a certain level of nutrients within the solution. Different plant strains will have different levels of nute need and there are many variable that will affect a given plant's desire to eat what you put in the soil. It is most important to keep a running journal of what you do so that you can go back to it later if there is a problem or question of what you did in the past with a certain strain. :)
