ok well i have been using florescent and they always make the plant take longer to bud and in the end produce less than a hps system you are using the perfect ratio for nutes....well thats similar to what i use 10-54-10 ...but i have just recently got a 400watt hps system and i have notice an increase in bud size in just one day....amazing how much of a difference they make but DO NOT STRESS florescent will work for now....i would recomend going threw HTGSUPPLY.com...they fuckin rock. and they have super cheap prices and i got my light in 3 days (cause i ordered over the phone) and when i opened the box it wasnt the system i ordered but one that was 100 dollars more (total upgrade) than the one i had origionally ordered.
i would also strongly recommend that you get some seltzer water to spray on the foliage and bud sites for CO2 supplementation
