And FYI- You can not just run the numbers like that. All formula's all NOT created equal and you can get Nitrogen for example from MANY different sources. THIS makes a HUGE difference! What form these elements are in is even more important (chelated or not)
A sad fact is that most growers do not have a clue what those numbers REALLY represent and how to interpret that data correctly. Couple this with the sad fact that most of the numbers that your shooting for are all off by a considerably error margin. AN claims to do specific plant testing yet there numbers in some of there formula's are way off as well. AN is ok for soil (still alarmingly over priced) but in hydro most AN plants show signs of over feeding......even when you reduce the dosage, the reason for this is because there is to much of one element and not enough of another, in other words the "ratio" is off and you will not fix that by reducing dosage.
UREA as an example is organic and basically consist of mammal urine. This is a source of nitrogen for a plant.
There are other forms of Nitrogen as well (mineral based to keep it simple).
So my point is that those numbers do not mean a whole lot if they are consisting of certain source materials. UREA as our example is organic and not available to the plants until bacteria first break it down and convert it to a useable form by the plants. If the grower is running sterile tanks what happens to the plants ya think? They start to yellow perhaps? I know this is a bit off the subject but thought I would mention it.
My main complaint with GH products is they are PURE salts almost and will destroy and cause leaching in plastics if ignored for too long and lots of build up. GH just bottles most of its stuff from other companies that actually make the nutrient. I think recently hey finally started making some of there own products in house. They are the most cheaply made nutrients IMO.
Moodster- the whole point of creating a nutrient profile was avoid wasting money on snake oils and other additives and what not.
Dynagro bloom formula has the MOST concentrated amount of P and K on the market so it is VERY cost effective to create a nutrient profile. Your at least spending money on the "right" things for excellent quality products.
Dynagro was the first company to make a hydroponic specific nutrient over 30 years ago.
And I am not boasting JUST
Dynagro, House & Garden Aqua Flakes also provides a very good ratio and nutrient profile that can be used for grow and bloom stages, there are others as well.
Cheers!
