Hello.
I do not have any experience with them, but from some looking around, General Hydroponics have a webpage of their feeding schedules that may help you out.
http://generalhydroponics.com/site/gh/docs/feeding_sched/GH-FloraSeries-REC-Charts.pdf
Here's a pdf of their feeding schedule, which contains the advanced and simple method of watering.
They have another schedule called "Drain to Waste", which I'm guessing is like flushing or something like that(not sure).

I have found another forum where they list a few different types of nutrients, and if you scroll towards the bottom, in
blue and
underlined you will find the General Hydroponics Flora Series.

TxOld Dude has a grow journal which might help you find more information on those products.

Note: If there are any boxes and such when viewing the pdf's on your browser, try downloading it then open it from your computer, and that should clear it up.
Seems like there are a lot of people who uses the Flora Series from General Hydroponics. Just hop on over to the growing sections or type in General Hydroponics in the search on top right corner and that should help you out a little bit more.
