Purple leaves???

Why is it that some of my plants will have purple leaves and some wont....same strain....same dirt...same nutes...WTF

Dont get me wrong..I like purple I only get these color leaves when its cold but its not on all the plants some leaves during bud will just turn yellow not purple

Cold temps will cause the leaves to purple. All of my indicas have turned purp on me they look cool smoke great no big deal. Could also be genetics. Yellowing leaves no nitrogen. Leaves will yellow and fall off naturally no big deal. Ur plants look good man

Cold buuurrr...looks sweet I don't think that will affect yeild or potency so purple on thats a nice shot....I'm indoors haven't seen that much just a little here and there during flushing nice plant

looks beautiful

bruising a plant does lose thc thats why you dont purposely bruise your plants until the last week before harvest. Looks nice doesnt do much harm, but its surely a detriment to the plant. I wouldnt worry 90% of pot smokers are completely ignorant, and would call it purple sticky punch, or purple haze or some garbage like that

upon second glance, looks like the strain, seems to mature into purple, id venture a guess that the purple ones are bigger and have yielded more, and the others will turn purple

also I got a some kushies 6 weeks into flower, and the genetics between them all, are the furthest from uniform. I have two 6 foot masterkush plants, only usually grow 3, and have completely different characteristics than the others. So they could just have different genetics slightly..

appreciate the coments guys....ya I been growing this 1 strain for about 15 yrs (indoors)..and every winter I get purple but only on some of the plants...It doesnt effect the taste or high

the photo were taken 8 weeks into flower...I usually get 6-7 0zs per plant

Yeah sounds like you need to check your min and max temps if your flower chamber drops below 60 deg f at night the purple comes out as some nute are not avalable in damp cold soil..I had a something like that just started as a red tint to the leaves I moved my room at that point anyway they do look bad ass like that anyway..at bout 55 deg when mine statred to go red whats your lights out temps dropping too? And are those up against a cold wall? maybe they get colder than the others?
