Check out my growlog my chillies are growing pretty well with basically a natural diet.
Calcium and magnesium are two of the elements that plants should have in luxury levels throughout their growing life so I dont muck around when it comes to making sure my chillies get the right stuff.
Silicon is the missing link in many fertility programs. This cell-strengthener also plays a role in photosynthesis and acts as a general tonic. Silicon can be a spectacular yield-builder. Recently boron has been identified as a silica synergist
Here is a titbit from an article called The Top 7 Plant Blunders by Graham Sait from Nutritech Solutions. the full article can be read here http://www.nutri-tech.com.au/blog/2010/11/top-seven-plant-blunders/#more-1503
6) Ignoring the Brix Builders
Brix is a measure of dissolved solids within the plant and it is a direct measure of photosynthetic potential. Photosynthesis is the most important aspect of crop production as it is responsible for 95 % of plant growth. The key minerals involved in photosynthesis are calcium, phosphorus, magnesium and boron. We often refer to this quartet as “the big four” due to their critical importance. It is a major blunder to ignore these nutrients and yet over 30% of the thousands of leaf tests we analyse each year, are deficient in all four minerals. Ideally, these minerals should be maintained at luxury levels in the leaf but over one in three tests reveal that all are lacking.
Calcium is directly responsible for the uptake of seven other minerals and boron determines whether calcium does this job. Phosphorus is the main mineral involved in sugar production and magnesium is a phosphorus synergistic. Magnesium is also the centrepiece of the chlorophyll molecule and is to this green pigment what iron is to blood.
The best way to build plant levels of calcium and magnesium is to use high analysis, Micronised Mineral Suspensions (MMS) which deliver the target minerals without the tag-ons associated with calcium nitrate or magnesium sulfate. Even phosphorus can be addressed with this technology, using micronised guano. This ancient bird manure is also an exceptional source of calcium (25 – 30%) and a rich source of plant available silica. Boron is best addressed with soluble sodium borate (Solubor or Dissolvabor) combined with a little humic acid to form a much more stable and effective boron humate.
