trying to flower this fucking 3.5ft plant

I have a plant that is preflowering,but I wasn't quite sure how much more light I would need been vegging for 7 weeks. Kinda strapped for cash but since I got it growing might as well finish it 23 watt cfls 5 of them used mg for ferts and switched to mg bloom ferts @ 1/4 strength.....also how do I add pics to my posts

Have you started 12/12 yet? Just wondering cause you said you were using bloom food. I'd use veg food up to 12/12 also I'd work your way up to half strength on the bloom food. As for the lights 5 23w is about 8000 lumen total I'd probably add more. More light=more bud. I currently have two plants and I'm using about 34,000 lumen. Good luck with your grow man.
