CFLS to HPS---Help ASAP! Please!

Ok,
First off I took some advise and purchased Peters 20-20-20, convienence is a must right now! I also switched from my Flourex CFLs to 300 watts HPS. I guess Im not to sure if my HPS is the same as most of yours . I bought them at Home Depot, They are compact flood lights,and are made by Sylvania, These will work right? My plant seems to be doing good, got a little bushier and taller first week into Flowering. I think its a Female, Im new at this so dont laugh. Instead of little balls its growing stems with leaves where the leaf and branch come together. I need someone to help me now because Im not sure how the feeding schedule should go from here on out. I also purchased some super bloom from lowes 12-56-9. Will some of you plant gods please help! You havent steered me wrong yet!
My Buddy looked at it(someone whois doing their own and I trust) and said it looked and smelled real nice.

it should be growing stems, balls are the last thing you wants because that indicated a male plant that does not produce buds. sound like your doing all right just let nature take its course

Thanks Cinci,
I guess Im just starting to panic because everything has gone well so far. Like I said I need some guidance now because this is the crucial part. I still didnt get a answer about the lights and my feeding schedule. Does anyone have any suggestions for me?
Peters 20-20-20. And super bloom 12-56-9. The plant seemed to slow in growth and start to get taller in the first week of flowering?

so ur flower an ur jus now noticing internode growth?? as for your light i have no exsperience with hps but it sounds like it workin, an the fert looks about right hi middle # for flower

no Ive had internode groth for a couple of weeks now.
How should I feed it? Foliage spray? or soil ,every two weeks, every day? Thats where I need the most guidance. Thanks.

thats realy up to you start out slow like 1/4 strenght every other water or so an see how she takes it, youll have to do some tweekin to find the perfect amount for her. an its not advised to have fert on the leave that can burn them fairly easyily

thanks cinci!
Ill post some pics real soon.
