Das what your'e doing at the mo sounds ok to me you'll have bud to smoke dont worry bout that..jus' don't expect a huge yeild or real strong potency but yes you will have bud...when it comes to 12/12 i would use the 7 hours of day light an 5 hours of fluoros...not 12 hours of fluoros as you'll have decreased yeild the sunlight will help you out alot...so yeh if it works don't fix it
