If a farmer had a crop of Cannabis Sativa that was chronically
affected with symptoms of lime induced chlorosis, what would be the
most cost-worthy remedy to salvage the crop?

Thanks

In order to determine the most cost-worthy remedy one would need to
know the size of the crop. Are they seedlings or mature plants? Are
they field plants or container grown?

They are between 7-10 weeks old, pot grown in ph controlled soil.

Lime-induced chlorosis is an iron deficiency in plants.

This article from Gardening Australia explains an inexpensive solution.
Prevent lime-induced Chlorosis
http://www.abc.net.au/gardening/stories/s717845.htm

"One solution that has been found to be most effective is a prepared
mixture of copra & coir, (two peat substitutes) soaked in water, to
which has been added a cup of iron chelates. This liquid is used to
backfill cores or holes that have been prepared around the base of
affected plants."
read the rest of the article at
http://www.abc.net.au/gardening/stories/s717845.htm it explains how to
apply the solution

Copra & coir are ground up coconut husks & flesh and can be purchases
at most garden supply stores.
Chelates are a potent source of trace minerals, specially processed
(chelated) to be quickly absorbed by plants.Iron chelates can also be
found in most garden supply stores or you can order it on-line.

One place to order it on-line is
