Being purple hinders yield?

[TGT]

I have read (and I'm not sure if this is true) that a plant that becomes purple from a temperature change is changing color because of a slowing down of the plants metabolic rate. The fluid in the plant slows, and this is what causes the purple coloration. If this is true then is this the reason a plant changes color when there is no temperature change?

Also, it is quite apparent true purple strains are less yield producing than other green strains. What is the reason for this?

Anyone with some experience or expertise about this please enlighten me. This has been a question that I have been wondering for a while now and never asked. Thanks in advance and keep it green.... or should I say purple? Lol.

Its changing color because of reduced P uptake when its cold.

some plants naturally change colors though.

Less P=less yeild. its an important nutrient in growth of cells for pretty much everything.

Sweet!!! i didnt know this... thats why my plants lost its purple when i gave em some more P! haha

There are a few Purps that yield very well and are nice and Potent. LVPK is a great strain.. My PP X Querkle is gorgeously dank

With all due respect TGT, I just think you haven't gotten your hands on a decent purple strain.

^^^^^^^^^^^^^^
Thats Outlaw's Gorilla Grape (Purple UrkleXDouble Purple Doja), a true purple strain that gives me 4+ zips of rock hard nuggets from a 3' plant indoors.
I've never subscribed to using temps to purple a plant, never saw the purpose behind it because it still not a true purple strain.
However, i can get a decent purple color from plants that are well flushed and taken to full maturity without ever hurting yield.

i grow grand daddy purple hybrids and can get 2 pounds dry off an outside plant; indoor i usually get around 8 oz. dry weight cured per plant. purple sativa from years ago can get a pound outdoor all the time and all the hybrids are purple. sweetgod is a great indoor yeilder averaging 6 oz. dry!

so unless its in the cold months; this blows your theory all to hell for the purple strains. purple erkle is another good 1.

The purple coloration is a result of anthrocyanin production/accumulation. It can be the result of activation of stress pathways, or produced naturally as a matter of course, depending on the plant's genetic makeup. It is possible to selectively breed a plant with purple traits over generations to produce more and more purple, with less and less need for stress, therefore not hurting growth rate. Keep in mind however that the production of this purple pigment (like all parts of plant structure/chemicals) is not free and does cost energy, which has to come from somewhere. Depending on the plant's genetics it may come from increased nutrient uptake, and/or reduced growth rate.

Hammerhead, I know there are probably many strains of purple that produce great, but in general they usually produce less than green, although I understand there are exceptions. Hammer, your LVPK I think I have seen and if it is the one I am thinking about it looks fantastic! I need a purp to grow like that definitely.

EvlMe2, I agree.

So is the purple coloration the result of Anthrocyanin accumulation or a lack of Phosperous uptake, I got two answers. Could it be that both are the reason as Nephrosis stated his purple coloration changed when he added phospherous?

Also what is the difference in chemical processes happening between plants that are genetically predisposed to turning purple as appose to plants that need cold to change?

Thanks for all the response and I will be on the hunt for a good producing purp.
