Will any strain turn purple?

Yes you can make any weak strain go purp. High K and cold root zone will do it. And MK has some purp in it so easy to do. Been thinking of turning this crop purp. Sence it's a small one. All I need to Fo to my MK is add ice and is so purp it stains your hands when trimming. But I said weak strain. A strong one will not change.

So all I need to do is add k and put water in my ice?

You realy don't want to add extra K. But ice cold water the last week will turn most purp at the end. This isn't realy something I would say to a novice grower. You do take a big chance of killing the plant if you don't know how it grows. For a novice I would say get your night temps around 60f and not mess with the roots. I don't know your level of growing.

Oh yeah i had this question as well, just a little different. are there any naturally accuring purple hair strains. or is it people who know there shit tweaked with there grow and got what they wanted. For instance carmelicious at amsterdamseeds pic has red hair, does this strain always produce red hair?!

Yeah there are naturally purple/red plants. Purple Urkle is the one I know but there are several. There was a pic on this site of a strain that was maroon, looked amazing.

Thanks man, and another quick question. Do these strains have different psychoactive effects or naw, just look a lot sexier lol.

Every strains effects are slightly different. I don't think that purple strains have a particular characteristic high to them... I did read and hear from people that purple cannabis is generally less potent than green cannabis due to the genes for these traits being linked. I don;t know if that's universal...I have heard a few people say that their purple buds are very potent.

Dropping the temps below 50 degrees at night continuously WILL turn any plant purple. Why? It's all because of phosphorus, when temps drop below 50 it causes phosphorus lockout. The thing about phosphorus in soil is once it's in there you cant get it out. Because it's a anion (negatively charged ion) it attaches itself to all the cations in the soil (calcium, iron, etc). This means depending on the ph and nutrient content of your soil Phosphorus can be almost impossible to flush out. It's in every "flower hardener" out there and plants don't absorb alot of it. This is why you can buy GDP or Urkel at any collective and its always fucking green.

This is mostly correct.

You need a day/night temp differential of 30 degrees to purple your plant...but the reason the plant turns purple is not because of a phosphorus lockout. All marijuana plants contain a chemical called anthocyanin which causes purple coloring, chlorophyll masks the anthocyanin color and you only see the green. Dropping the night-time temps reduces chlorophyll production and allows the anthocyanin to show through, thus the plant changes color. Same concept as tree leaves changing color in the fall.

The problem with doing this, and why purple strains have been historically less potent than other strains, is that chlorophyll is necessary for photosynthesis. Weaker photosynthesis = weaker resin production = weaker THC content.

Dropping the temps stops chlorophyll production because plants stop absorbing phosphorus. What you said isn't really a contradiction.
