    my plants are all 17 days from seed, just up-potted this morning.


    i tested ppm in tap water and its 0045, obv very soft


    I`m thinking i need to start adding calmag, but want to hear from some experienced growers whether or not this would be a good idea for my 17day old girls.


    Thanks

    45 is low, at 17 days in i would be 2-3ml/g minimum atleast in soil.

    I’ve never used anything from fox farms but if they build their soil decent you shouldn’t have to feed it anything for a few weeks.

    Water softener or municipal?
    If you use a water softener, the salt will hurt your plants in the long term.

    sigh


    heres another question for you guys


    i was told i needed to increase my humidity ( was only high 30s) and could do so by having humdifier run during lights out, well boy was he right, i just opened tent to check on the girls and the entire tent was soaked, hydrometer reading 99% and plants looking drenched . i think i missed a pointer or two when he was telling me, like maybe keeping a vent open or keeping my fans running? i dunno.


    did i just mess them up? this all happened within 6 hour lights out window

    It’s best to use a humidifier with digital controls that will shut off at a point

    Ya i def agree with that, after this morning its the next thing in my amazon cart, going to have a look now.


    they all seem ok, only thing i did notice was the leaves seemed a little dryer, but with all that moisture on them from humidifier and then lights coming on, i assume would have this effect?
