    Default ppm guide for soil

    Does any one have a guide for soil ppm or is it the same as the one for hydroponics.



    A basic guide you can use for your plants (Hydroponics):

    Seedlings/Clones: 400-600ppm
    Early Veg: 600-800ppm
    Late Veg: 800-1000ppm
    Early Flowering: 1000-1200ppm
    Mid Flowering: 1200-1400ppm
    Late Flowering: 800-1200ppm

    Default PPM's in soil

    Use the half and only at every other watering to avoid trouble and build-ups of salts. (You can increase later when the medium becomes depleted in own nutrients, but if it's amended thoroughly from the start a 1/2 to 3/4 strength solution should suffice throughout the season.)

    The more aerated and stable regarding pH you could boast those ammounts, but you'll need to try out things...

    Please note that most soil growers only feed every second watering to avoid salt buildup.

    Hope this helps.
