Hi all, I thought I would share my experience and knowledge about this feeding formula. I have personally been using this for my grows and 100's of growers worldwide can attest to it's efficacy.
Our plants have needs as far as nutrition goes and we all try our best to make sure they have everything they need to give us the best meds possible but there is so much misinformation out there. The makers of these feeding products do not have it in their interest to tell us the cheapest ways to get the most out of our girls. As a matter of fact I am pretty sure that most would find it general knowledge to never feed them more than 50% of the recommended strength printed on the package.
I know this is already starting to feel TLDR for some, but the few more paragraphs to follow come from over 100 pages of posts here:

But in the name of brevity here is the scoop and the why will follow.
Buy this: http://generalhydroponics.com/site/index.php/products/nutrients/maxi_series/maxibloom/
and use 7 grams per gallon of water, use it at half strength for cloning, then after rooted and until flush run at full strength 7g/Gal.
That's it, thanks for making it this far, oh almost forgot if you use coco add 1g/Gal of Epsom Salt.
Ok back to the splainin.
Here locally you will find the 2.2lb bag for about $16 plus most places give a 10% discount if you bring your girlfriend and they ask the guy for it. so for $14.40 we get 998grams for a total of 998/7=142.5 gallons of food for our girls. which makes our cost $14.40/142.5=$.10Gal for our food buying just the small bag locally.
I can assure you you will not find your plants lacking in any way from using this food, but some people still do use additives though they definitely are not necessary. My 420 cup entries will be from plants that ate only Lucas formula for their entire lifespan. My current crop had some 45 day finishers so I tried using Koolbloom at 1.2 grams per gallon on top of lucas during the last 2 weeks prior to flush to stress the plants out and ensure their timely finish and get the most out of their short lifespan. I can say I do know the Koolbloom powder definitely works to kick start the flowering, used for just one watering at half strength the day after the flip had flowers showing the next day for me, much sooner than the week or so it took for the ones without the kickstart.
Now a lot of people will say how can it have everything, but at 5-15-14 it does, it has all the nitrogen you need for nice big green veg but not so much you have veggie flowers. It has loads of yummies for your roots and buds, which may go to waste when not rooting or budding etc... but at $.10 a gal you can stomach a little loss and not have the hassle of trying to feed them only vegging or only flowering nutes . Give it all to the girls and they will take what they want and leave the rest, give yourself and your wallet a break and Keep It Simple Stoner is what it is all about.
On a side note, feel free to disembark if you intensely hate being taken aside, I have heard the term chemicals applied to non organic food. There is always misinformation out there about things but this is a pretty big area to let it go unchecked. AFAIK there are not any chemicals in any nute out there, there is organic based and non organic based nutes. The difference is as follows:
Organic nutes are nutes the way they are found in nature, in their complex forms inside other compoounds, typo or punny, you decide.
Non organic nutes or 'chems' are simply refined elements from those organic compounds. You know Nitrogen, potassium, phosphorous etc. These my friends are not chemicals, these are Elements in their rawest purest form.
Now the benefits of each:
Organics are harder to overnute in soil because organics do not have nutrients readily available to your plant. They are in forms the plants cannot ingest, however lucky for you there are bacteria who do that job in the soil and they will not over eat so much as to over feed the plant. So it is pretty stoner proof in regards to harming the plant.
Non organic nutes however have 100% of their nutrients available to plant immediately upon exposure, no middleman is needed. Because of this if you do not measure accurately, keep your ph in proper range for absorption or overfeed your girls they are going to show it and let you know. More so in hydro and coco still because dirt has such great balancing capacity for ph and absorption of excess nutes.
Ok off my soapbox hope this helps make life sweeter and cheaper for some.
