what locks out what???

The reason nutrients are split into two parts is because of Ca and S dont play well together in the bottle. None of the 'two parts' ive seen have Ca and S (at significant levels) in the same bottle (Copper/Manganese Sulfate are not a significant level of S). Ca in the 'first bottle' and the majority of the S in the 'second'.

As stated, almost all 'first bottles' have Calcium Nitrate & Fe, two ingredients that are in most cal mags. The only difference between BC Boost and Magical is Magnesium Nitrate vs Potassium Nitrate, and and another form of Fe (the Cl is negligible). Like I said, most 'first bottles' have the micros, but technaflora does not. Yet they still recommend their 'boost' bottle first. There is something in this bottle they want diluted into the reservoir before adding the 'second bottle'.


So... because technaflora recommends their 'boost' first, there is no S in the magical, and these two are so similar, i think it should be added before the 'second' bottle, but im not sure it matters all that much.

gotcha. thanks doc!

PLANT NUTRIENT INTERACTIONS

Antagonism
Mulder’s Chart shows some of the interactions between plant nutrients.
High levels of a particular nutrient in the soil can interfere with the availability and uptake
by the plant of other nutrients. Those nutrients which interfere with one another are said to
be antagonistic.
For example, high nitrogen levels can reduce the availability of boron, potash and copper;
high phosphate levels can influence the uptake of iron, calcium potash, copper and zinc;
high potash levels can reduce the availability of magnesium. Thus, unless care is taken to
ensure an adequate balanced supply of all the nutrients – by the use of analysis – the
application of ever higher levels of nitrogen, phosphorus and potassium in compound
fertilisers can induce plant deficiencies of other essential nutrients.

Stimulation
Stimulation occurs when the high level of a particular nutrient increases the demand by the
plant for another nutrient.
Increased nitrogen levels create a demand for more magnesium. If more potassium is
used – more manganese is required and so on.
Although the cause of stimulation is different from that of antagonism, the result is the
same – induced deficiencies of the crop if not supplied with a balanced diet.
High levels of molybdenum in the soil and in the herbage reduce an animal’s ability to
absorb copper into the blood stream, and ruminant animals grazing these areas have to be
fed or injected with copper to supplement their diet (see Mo/Cu dotted line).

Mulder’s Chart
ANTAGONISM A decrease in availability to the plant of a nutrient by the action of another nutrient (see direction of
arrow).
STIMULATION - - - - - - - - - - - - An increase in the need for a nutrient by the plant because of the increase in the level of another
nutrient.

good info bro!
