    If you have a hydro shop near, or even a good nursery you can buy the two fertilisers needed for Growth and veg !
    check the grandp grow guide for the correct NPK rating on both.
    Or you can use a tomato grow food if you like, Or start a compost heap !

    Ferts for vegging stage should have a higher or equal N (1st) number, such as 20-20-20.

    Ferts for flower stage should have a higher P (2nd) number, such as 10-54-10.

    Interesting. My BioCanna Floracion, specifically formulated for cannabis has K the highest. As do tomato ferts. And websites I have visited confirm that K needs to be high for fruiting and flowering.
    But Fox Farm fruit and flower puts P highest.

    NPK for grow 20-10-10
    NPK for bloom 10-10-20

    rough idea anyways

    Quite, higher K for blooming.

    I've seen the P and K flipped for some products as well. Different theories I guess. The plant needs all three nutrients in both phases.
