Following is a formula which was developed by our local Chemist, Guru Gilbert.
It has proven particularly successful in bringing out the Colour Potential in the leaf.
It is for root feeding only and the solution is introduced by a syringe into the
gravel.The shelf life of the Vitamin B1 is unknown in the solution so it is
recommended to make up volumes sufficient for a month or so.
