you need to add perlite to your soil when you mix it. with mj the roots love air. if you don't add perlite when you repot your opening yourself up to all sorts of problems such as root rot to name 1. i'm very suprised that none of the above posters noticed! i like to use at least 1/3 perlite but recently have been using even more than that with excellent results. without perlite the roots just suffocate. your plant looks good(a little stretched)i just wanted to give you a heads up before you have any problems. also if that is peat,which it looks like, you need to make sure you add 1-2 tbsp dolimitic lime per gal of soilmix to raise the ph to the low 6's. peat is naturally very acidic and will cause nute lockouts if not counteracted with lime or another akaline substance, i think plaster will do the same but dolimitic lime is easy. it's hard to add to much. i have added as much as 8tbsp to a gall of soil as an experiment and the ph was still only 7.0. just be careful because they also sell hydrated lime which is much more powerful than the dolimitic lime and can be easily overdosed.
