Need some more details, How much do you water, how old and what stage are the plants in, how much are you feeding them and what, what kind of lights etc.
sorry i clicked the wrong botton and only posted that part... i got the plant from a friend who didnt want to put the time into it anymore i dont know what he did .. but i do know he used some miricle grow a couple weeks ago.. and the soil was really dry when i got it so i think it was underwaterd. im going to go try and get some pix up
You could probably top it. Cut the top right off just under the first or second set of leaves. This will give you a bushy plant with more than one cola (bud) on it.
You can use it if that is all you have. Just use like a 1/4 of the suggested amount to start. Then I feed every other watering. But do this after re-pot it cause you will have to water then anyways, lol. What you using for soil mix?
I use a promix and add my own nutes to it. Promix contains meat moss, perlite, vermiculite or lmestone. You can get it at any garden type store. Try to stay away from the soils that have nutes in them already. I like to add my own for better control. As for nutrients for vegging it, you need one that lots of N nitrogen in it. For flowering you will need one that has more phosphate and potasium than the nitrogen.
