    I would check EC every time mixing nutes and adjust based on starting point. I start with zero EC so I have no idea how to feed a plant on hard water.

    With my water it fluctuates, i tend to use the highest number of my tap and mix away, worse case your abit light on feed. Much better than being to heavy, wait a day and you can always add some nutes.
    Your final numbers will be determined by size age and health of plants and stage of grow..

    I was all ways told to never go higher than 1.0 ec and that that was when switched to flower wot should I aim for max dose.

    My tap water is currently 0.6 ec
    For young plant ididnt want to go much higher in case they burn but after I had half stated does of nutes it goes up to 0.8-0.9

    Your water is.6. Not 0 . .8 sounds like a good number for very young plants.

    Hi my tap water fluctuating between 0.4 and 0.8
    This is quiet a large fluctuation i can not recall seeing such a fluctuation. Seen a few that go up and down by a point or 2 never by .4 . What EC pen do you have? and is it calibrated?

    Well water did cross my mind when i was replying to the thread. Out of interest what is the ph like and what system or substrate will you be growing in?

    You said after adding half nutes, so you know they have what is needed to grow, let them grow watch the plants, never trust a meter, only use it at a guide,
    Kbag has a valid point about calibration! But my well water does see these fluctuations based on water usage in my home and environmental conditions.

    Define young plants
    1-2 weeks
    4-6 weeks.
    I keep my ec low when the plants are small and establishing a root system, then once the roots are established, you will see a major change in the plants growth rate, at this time i bump the numbers up as the plant will require the nutrition thru the spurt, to low and you just get slower growth.
    Too many people are tempted to overfeed the plant trying to get this growth spurt, but you must wait patiently for it and react when it comes.
    Are you doing photos or autos

    No I don't I'm afraid
    I did over dose last grow and ended up flushing the in Bath cos ec runoff was around 1.7 and stunted one of the plants and all turned yellow two soon

    I have no experience in coco, but to me 7 sounds high.
    In Rdwc during veg i try to be about 5.8-6.3 lower in flower.

    I know that coco has some unique tendencies, with ph but forget what they are.
