    Default 3 week old seedlings not growing

    Hey everyone,

    this is my first grow my setup consists of

    36"x 36"x 72" Grow Tent
    600w full spectrum led light with dual chip (has bloom and veg mode)
    humidifier
    oscillating fan
    6" c02 filter exhaust

    the country i live in has no measurements of NPK and importing soil or fertilizer is a hassle and costly thing
    grow medium is (organic potting soil) 50%
    plant compost 20%
    perlite 30%

    feeding every 2 to 3 day ( ph balanced tap water)

    3 seeds that are northern lights (feminized) from royal queen seed (photo period)

    all seeds germinated within 2-3 days and were placed in plastic cups with a dome, the domes were removed 2 to 3 days later

    So within the first 7 days everything seemed fine however from day 8 to day 16 there was no progress at all so i decided to move them to a bigger pot thinking that they outgrew the cups fastforward to day 21 the plants did not show any signs of improvement

    I am not willing to let them go yet since getting the seeds is such a hassle, i am considering flushing the pots with RO water to see if maybe the roots are clogged with salts

    Personally I wouldn't go flushing a seedling, itll sit even longer doing nothing, a lot could be happening allready under the soil that little is shown up top yet
    Temp, humidity play a big part now more than watering the pot

    I'd fight anyone that says anything other than over-watered and drowning.

    As above have said, let them be...roots should be growing out in search of water at this stage so don't give them too much otherwise you will have issues

    I agree with the over watering comment. The leaves are slightly turned down, the plant is in a rather large pot for its size (which is ok just remember the more soil the more water sits in it and therefore the longer between waterings) if the plants are overwatered the roots will have trouble getting air and all this will slow growth. The roots may be establishing themselves nice and deep.... However I've onserved the growth is proportional from above and below soil.

    My advice, let it dry out till the seedlings leaves are no longer pointing down and begin to lose the papery feel. Theyll get more like a slightly moist tissue when they are dying for water. Then give it a little water. Don't douse it. Remember the roots like air and it's a good deterrent to root problems when you allow the soil to dry out good.

    I find that bringing a healthy plant to stress by with holding water and notes at intervals causes wonderful big plants. So, don't be to worried about it. The plants may end up licking you for the mistakes you make. Lol

    nobodys mentioned the Phing of the water

    been told not to bother phing up or down the water as the soil will naturally correct it, that is unless you live next to an exploded nuclear reactor!!

    that soil looks moist as feck let em go dry for a bit.
    skin it roll it lick it twist it.
