    well, what does the instructions say? i usually start on the weak side and get gradually stronger until i'm giving them almost twice the recommended amount (using 15-30-15)
    take care not to burn them and check soil ph regularly.

    get an ec meter & follow the feeding instructions on the fert before u kill the plant!!
    Feeding not enough will slow it's growth. Feeding too much will kill it.
    set ec at .5 - .8 for seedlings, rising to 1.0 - 1.2 as it gets more leaves.
    Then gradually increase to peak at 1.8 a few weeks before harvest.

    Flush out with gallons of ph'd water between steps in nute strength.

    u won't know what ur doing without an ec meter!
