Sorry, my error. Somehow I managed to skip that line and jumped from; "so my question is how un-organic is it" right to; "whats the big difference between organic and synthetic nutes on the final product if they have the same N-P-K value??"
　
I cannot give you percentages but:
　
Grow Big, neither the soil formula or the hydro formula, is advertised as being 100% organic.
　
Tiger Bloom is not advertised as being 100% organic.
　
Big Bloom is advertised as being 100% organic, a blend of "natural & organic" materials.
　
The other Fox Farms products you asked about are ones I have not used so you may wish to Google Fox Farms and see what they claim.
　
The Fox Farms dry nutrients are claimed to be 100% organic.
You may receive any number of differing beliefs about the difference in 100% organic fertilizers etc. and mostly organic fertilizer etc. and non-organic/chemical fertilizers etc.
　
To a total 100% organic grower someone saying use Fox Farms products is heresy.
　
To someone in love with chemical fertilizers they will likely say that their chemical fertilizers work as well as Fox Farms products and if not quite as well still close enough to being as good so the difference in price to use Fox Farms products is not a good value for them to spend the extra money.
　
Myself, I like them and use them. I use the three I commented on above and in my experience they work very well. Any slight measuring mishap is not going to cause a problem, they are somewhat forgiving in that, but it does not take much extra chemical fertilizer to do some real burn damage.
　
If someone is only growing for themselves in fairly small numbers of plants the expense is really not that much extra for what you get in return, at least in my opinion. The Grow Big will normally last fairly long because you will only feed so much during the vegetative growth stage, which is normally a good bit shorter in duration than any flowering time, like half or less in many cases. So it goes a long way for someone with a small garden.
　
The Big Bloom tends to go fast. It is not highly concentrated like the other two so if you use it as often as recommended on the bottle/jug even a gardener with a smallish garden may use much of two quarts during flowering.
　
The Tiger Bloom is highly concentrated so again it lasts fairly long. Not as long as Big Grow because you will feed so many more times during flowering than while in a vegetative growth stage but again for someone with a smallish garden one quart should get them through each grow.
　
That is figured on how I use them, as in Big Bloom and Tiger Blossom together for each feeding. If someone alternates them or comes up with some other feeding schedule that would not use both at the same time all the time that would make each last even longer.
　
Part of the organic plan is taste. In my experience if you flush well and then dry and cure properly if there is a difference in final taste it is not dramatic. It may show up slightly more in some strains but in others it won’t.
　
Another part to all organic is you are not feeding the plants but instead feeding the soil. Arguments have been raised as to the actual degree of importance to the final results that can be compelling for both positions, as in if feeding the soil is actually better in the end than feeding the plants or not.
　
In some cases it may all come down to grower knowledge and skill and diligence and setup/conditions as to if one person will get better results going 100% organic or not, and even genetics can play a part in that some strains are bred to grow best and taste best when grow using chemical fertilizers. There are not many but there are some and then certain other strains just by chance will be effected to a greater or to a lesser degree by what type of fertilizers you use. In some cases it will work better than in others.
　
You need to factor in every possible detail and then see if it is a better value for you to go 100% organic or partially-mostly organic or chemical.
　
I am very pleased with what I use. I will not say it is the very best but I know it is not in any way at all bad. It all comes down to what is most important to you and what is a value to you.
　
Some medical growers will not use anything other than 100% organics because they do not want to possibly take any unnatural substances into their bodies. To them that alone is a valid argument for growing 100% organic.
　
Others will just say it is better overall but as I said while it may very well be best for some people but it might not be best for others/everyone, or at least not enough of a value for everyone given all the variables that factor in.
　
You need to decide what is important to you and what is a value to you and then go with it. Later if you are not fully satisfied or if you just want a personal comparison to go by then you try the other.
It is not as if you will be locked into one way of doing things for life and it is not as if the difference in price when possibly making the switch to try the other will likely break your budget.
　
So collect a few more opinions and then weigh everything and make a choice and see how it turns out.
Make a decision and then pull the trigger.
