What set-up? (what are you using now?)
Low or no nitrogen for the flowering stage.

This info is readily available all over the web. Look-up any hydro shop, and you'll likely see what mostly everyone else in here uses, and what those nute ratio's are. The better quality nutes you use, the easier your job as a grower gets.
Would recommend Fox Farms nutes 3-part system, Canna Terra products, the General Hydroponics line... There's other more expensive nutes, and some that are cheaper, but I always stick with what has already been proven to work well for our purposes. (most expensive doesn't mean it's better)
If you decide to order some, make sure it's for your growing system. (soil, hydro...)
