    they usually start lighter green then get darker.

    looking good so far.

    use your EC/ppm meter to tell you how they are feeding:

    if at 200ppm, what is it the next day?
    if it's at 190ppm, thats good. they are eating and your ppm is pretty close.
    it at 220ppm, it's too strong, they are drinking more than eating
    if at 100ppm, way too weak. make it stronger.

    make sense?

    I get what you mean. But a couple things about that:
    1. I have one of those bluelab ppm sticks so they don't really tell me an exact ppm number.
    2. None of my roots have touched the water yet so I'm not sure if the ppm would be affected yet? Any nutes my plant's getting are from me top feeding moreso than anything. Although I will say the water is splashing a lot in the reservoir so maybe it is hitting the roots.

    And oh yeah, that was always something I wondered about DWC and that is how don't the roots 'drown' for lack of better words when they've grown long enough to reach the water in the reservoir?

    get one of these then:https://www.amazon.com/HM-Electrica...F8&qid=1520605371&sr=8-3&keywords=HM+EC+meter

    only 20 bucks. and EC is better than PPM anyway.
    if it's growing, it's eating.
    airstone provides O2

    I change out the reservoir every four days and today is a scheduled a change and I'm definition going to have to lower the ppm to 200 cause as ucan see the top leaves are a bright green and the first ones are starting too change color at the tips.
    Probably going to top feed with a gallon of distilled water I just picked up for a couple days. Thoughts?
