I was thinking the same thing, but then thought couldn't it be a genetic trait that causes the deficiency? For instance in humans, some people have no melanin in their skin which causes albinism (you seen this in people with white eyebrows, white hair. also rabbits get this). So having no melanin is due to genetics and having less than normal people is a deficiency which causes your skin to be colorless.
I don't think it means the plant is unhealthy in anyway, it probably doesn't uptake a certain mineral or something because of its genetics which causes its colors to be different.
Maybe someone with a background in botany knows more? I'm going to look into this more, maybe email "JC", interesting topic.

At 2:45 / 5:46 he discusses the purple deficiency.

Here is a quick little read from HighTimes...has some descent info...although I believe there are more degrees of purple than he states.
Purple Cannabis
The origins of purple cannabis are as much of a mystery as the origins of the plant itself. However, purpling is as natural as the changing colors on the leaves of deciduous trees in autumn, which is attributed in part to the pigment anthocyanin. Anthocyanin expression is controlled by both genetic and environmental factors. Purpling is a simple dominant Mendelian trait, with quantitative expression.
Environmental Factors
Several pigments are responsible for color in plants: chlorophyll, carotene, xanthophyll, and anthocyanins. Chlorophyll is the pigment in chloroplasts of plants that reflects green light. Plants use the energy absorbed by chlorophyll in photosynthesis to produce food for their growth and development. It is continually broken down during photosynthesis and being replenished by the plant.
Carotene and xanthophyll are pigments that reflect orange and yellow light respectively. Both are present in the chloroplasts, with chlorophyll enabling the plant to absorb a wider range of wavelengths of light and thus capture more energy. These pigments are present in such small quantities that the more dominant chlorophyll typically masks them.
During flowering, with the passing of summer, days become shorter. The phytochromes, the light-sensing mechanisms in leaves, recognize the shorter day lengths. The shorter days and lower temperatures arrest chlorophyll production. Chlorophyll breaks down faster than it is replaced, allowing the yellow and orange pigments to be unmasked.
The molecules reflecting red wavelengths, anthocyanins, are water-soluble pigments that occur in the cell sap, creating the red, pink, and purple hues. These pigments may not be present during the summer, or vegetative cycle, but their formation is encouraged during a succession of cool nights and sunny days. During these days when photosynthesis and chlorophyll production are decreasing, an abundance of sugars accumulates in the leaf. The cool nights promote a separation layer of cells in the petiole—where the leaf attaches to the stem—that prevents sugar from flowing out of the leaf, and also arrests the flow of nutrients into the leaf. The formation of anthocyanin requires bright light, a diminishing water supply, and the accumulation of sugars trapped in the leaf.
Another factor that can cause purpling is nutrient deficiency, generally phosphorus. Although these stunted plants may bedazzle the novice, they are typically quite distinguishable from naturally occurring anthocyanin expression, due to the other visible adverse side effects of nutrient deficiency, such as leaf and bud malformation and low calyx-to-leaf ratios.
Genetics/Degrees of Purple
The discussion of Mendelian genetics, anthocyanin-expression traits and which genes at which loci influence them, mean and variance, and heritability in quantitative inheritance is beyond the scope here and will have to be left for a future article. However, there are easily observable indicators that aid in the quest for the purple kind.
The first degree of natural purpling in cannabis could be characterized as occurring exclusively in the leaves and petioles: the colors of autumn appearing in the fan leaves during cooler temperatures and close to harvest. The Akala hybrid is a beautiful example of the first stages in this level of purpling...
A more expressively first-degree purple hybrid, the Blue Ruskaya also responds to the same cooler environmental conditions, but, in addition to the fan leaves, the cola leaves also dominantly display its colors...
In the search for purple hybrids, one factor to consider is, although purple leaves are pretty to look at during flowering, most of these are manicured away post harvest. With the onset of extensive purpling to the base of the bud leaves, we are beginning to gain some bag appeal, as the California-Orange and Blue Ruskaya nugs reveal.
The second degree is where purple begins to manifest beyond the leaves and on to the calyxes. The AB Hybrid is a jewel of an example of this level, purpling very dramatically in the leaves with splashes amongst the calyxes. We’re on to some serious bag appeal now...
Tasting of geraniums and cocoa, the Black Russian (a Blackberry x AK-47 hybrid) also falls into the second-degree category, but is unique in that the leaf largely remains green. It is the calyxes that are primarily affected, and these show purple from early flowering on through harvest even under extremely high temperatures, a trait for which it was bred from its Blackberry mum.
This brings us to the third and final degree of purpledom, the Blackberry. This rare phenotype exhibits a deep, dark purple bordering on black on all its calyxes (even nodal), under all circumstances except extreme high temperature, from the start of flowering through harvest...Even the trichomes of the Blackberry are purple, which makes extracting bubble hash a rewarding process, as both the water and the hash end up purple.
Therein lies the quest for cannabis breeders. As I raise a toast of vapor from purple bubble hash nested upon a bed of purple kind filtered through purple bubble water, I feel not unlike a king, and I decree: May the royal purple herb grace your garden, and may we all be blessed with life’s little luxuries.
