Purple Leaf Tips

Anyone know whats going on here? is this nutrient deficiency? temperature? or just a strain characteristic?

Im curious too because mine looks like that.
Ive looked around and it could be phosphorous deficiency,
but i think its just the genetics because its doing no harm to my plants, and your plants seem to be healthy also

Mine look like that as well. From what I can gather its the colder weather that causes the purple leaves. No worries.

I've been told its cold weather but I've also been told its the strain genetics. Either way I live in an area where its gets a bit colder these days towards harvest and mine have always turned a bit purple. They have always been good to go. So ya no worries man.

Yep, no worries, That usually happens to mine as I also live close to Canada

good to know. I tried moving them in at night when the temperature would drop and it didnt seem to have an effect so I wasn't sure WHAT was causing it...

Moving them inside at night is good too man, I bring mine in just cus the dew and to get them 12 hours of dark as well. What strain?

Strain. It's still upper 80's where i'm at and mine look just like that. I'm on top of my nutes too. Don't trip and enjoy the pretty-ness.

morning sun is the best sun.....just in case you didnt know

phosphorus deficiency will cause the stems to turn purple, not the leaves until later and major deficiency.
but xxJDxx your plants look indoor, or did you just take em in for pics lol. how cold could your grow room be getting?

i had a roadrunner auto that had purple leaves and some purple bud on it...there is no purp genetics in this strain at all...im growing indoors in a grow box...the lowest the temps get is 76-78f and the highest being 85-86f...so with no purp genes in it..and the temps staying pretty warm...mine turned purple....so it must be something other then just cold weather and genetics causing this

Nope they are OD. Not sure of the strain, they were clones from a 'mysterious' source.....

Cold weather is the cause. Don't worry.
