Noob here. Needing some quick advice.

I'm wondering if this setup is going to be ideal for one plant, Its a 3x3 box. with 2 100watt daylight 6500k CFLs, Im using Vigoro all purpose 19-6-12, and the soil is a peat moss and perlite mixture. The plants been doing alright but the leaves are starting to turn a little yellowish off the stem. and the main stem is starting to turn like a reddish brown.

easy on the nutrients .. peat moss has a shitload of organics in it already .. if i was you and only IF you could pull it off i would re-pot it into just some regular ole potting soil with either perilite or sand mixed in with it making sure to shake off most of the peat moss .. then water it with plain ole water (5.6 pH) till you get your nute burn taken care of them slowly reintroduce the nutrients at half strength gradualy increasing the dose over time and still only nute the plant about every other or every third watering .. hope this helps PEACE !!

I'm assuming you mean 3'w x 3'L. What's the height? I'd suggest at least 5 foot if you want to have plenty of room for the plant to grow without running into the lights.,fan, or other stuff you have in the grow box. You can get by with less, but you aren't going to be able to veg your plants very long before flowering without them getting 3 ft+ by harvest time. Also, the nutes your using are all right for vegging, but your going to want to get something else for flowering. During flowering you want the ratio of N to P to be closer to 1 - 2 because the plants need more P for bud production and less N for leaf and steam growth. Jacks classic all purpose and bloom booster are supposed to be a good full life cycle fertilizer set (I'm still using fox farm, but plan to try Jacks on my next grow), and you can pick both of them up for about $15 total.
