so, i've taken over my roomates grow-project, because i've got tons of free time and she wasn't paying them enough attention in my eyes. haha they're doing very well so far with what she has done which is just standard watering.. they're about four weeks old or so now.. probably about 6-7" tall and i've already taken 4 males out of about 10 plants. nipped them quickly. im in the south where our temps arent extremely cold at night and its been rather nice in the day about 70 or so.. so they are coming along rather nicely. not so bushy though? is that ok? some of them are getting a little bushy but no "branches" so to speak.. also, with them being outside on the porch, was wondering if there was a certain temperature they should not be exposed to as far as a low (of course not freezing). also, haven't fertilized them whatsoever as of yet.. where do i start VERY SIMPLY fertilizing? miracle gro should do the trick right? since they are growing outside this time of year i'm assuming ill just be nurturing this plant through the winter and such and then have a nice healthy plant to produce bud in the spring/summer, correct? thanks for any advice in advance.
