To answer the question, Borax supplies 'boron' to the plant. Boron deficiency is evidenced by withering and dying growing points, brittle & interveinal chlorosis of upper leaves. A Boron deficiency can indicate and/or cause a calcium deficiency since boron improves calcium intake of the plant. ... Immediate treatment is by folar spray.

While this is a specific cause and correction, diagnosis is not simple and easy for most people since many problem symptoms look the same. Generally I believe this type of problem is an indication of depletion or lack of 'micro elements' to the plant. ... 'I would': apply a folar spray to include the micro elements' for faster remedy of the problem and apply micro element supplement to the root zone of the plant for long term plant support. This does not tend to be a major problem with plants in the ground and proper use & application of fertilizers with micro elements, but is prevalent with container grown plants.

Inside plants generally benefits from folar misting with a low dose mixture of micro elements.
