Never used any thing to boost flowers besides regular bloom nutes. I have herd they work well if done right, but can mess with the finished products taste. Especially if you fail to flush it all out. Since this is your first grow, I would just try and see if you can make it a successful harvest with out trying to add to much. Over loving a plant will kill it WAY faster then most people think. Also change the light cycle to 18/6, as it will give you faster growth results. The plant really only needs about 6 hrs of dark time to get sufficient root growth. Go out and buy some more lights, like the one that OSGS has posted, and make sure the PH stays in check. Oh yeah, blue/green for veg, and red/orange for flower is the color spectrum's to have for the respective cycles.
