calcichew is the equivalent of 500 mg of calcium, it's tempting to create a mix of water with nutrients and a pill of calcichew and give it to the plant and has colecalciferol which is vitamin D and has some magnesium as well...
An article that I found:
"Vitamin D and related compounds (hydroxylated derivatives and glycosides) occur naturally in certain plants. The metabolism of vitamin D3 in Solanum malacoxylon Sendtn. is similar in certain respects to that in animal systems. There is also evidence that vitamin D3, plays a role in processes regulated by Ca2+ in plants. Vitamin D3 possesses plant growth substance activities and in particular enhances adventitious root formation.
Evidence that vitamin Ds could affect Ca2+ uptake was lacking for plants. For this reason, the radioisotope 45Ca2+ was employed to measure the uptake of calcium into shoots of micropropagated potato plantlets (Solanum tuberosum ‘Russet Burbank’
treated with nutrient solutions containing vitamin Ds (D2 or D3 at 0, 10, 25 or 50 mgL-1) and Ca (3, 5 or 15 mM). Vitamin Ds at 25 mgL-1 were most effective at improving 45Ca2+ uptake into plantlet shoots. At higher concentrations (50 mgL-1) vitamin D3 did not stimulate 45Ca2+ uptake beyond that achieved at 25 mgL-1 and D2 was inhibitory to uptake. It was evident from this study that vitamin Ds improved 45Ca2+ uptake into shoots of micropropagated potato plantlets and that D3 was more efficient in this capacity than D2 or a combination of D2 and D3. Vitamin Ds apparently play a similar role in both plants and animals by affecting Ca absorption and Ca-mediated cellular functions."
