what nutes are you using and you should only water when soil is completley dry oh and dont use butes for about 2-3 of begginging of gorw are you doing 18-6?

yea i am doing 18/6 no nutes added yet just pure rain water

all of the plants look really healthy i think just little

Wow I thought mine were small.
They do look healthy but more like a few days old, not a few weeks. Where did you get your dirt?

its black magic from the plant store here

they have been like this for about a week with no new growth their not as bushy as others i see could it just be the strain or what i really need some help

mix your backyard soil in a mixer with a little horse crap/manuer of how ever you spell it. just make sure you dont burn the roots.

they look hungry. Check the ph of the water it should be around 7.0, how often are you watering? the soil needs to completely dry in between waterings. Get some nutrients meant for weed. Your plants look like mine after 1 week in soil.

after i wait till the soil is dry do i need to water them really good? or just a lil at a time

let the soil completely dry and water until you have 10% runoff. It is counterproductive to keep the soil moist all the time.
