need help why is my plants stem purple?

well i have 2 clones i have been growing for 3 weeks and dey started out good untill noww the stem is turning purple whats wrong with them?can someone help me please

thats nothing. it usually means colder temps but dont worry i have it on my stems too

idk about the colder temps.my clones stems turned purple also.my temps are kinda high.its all good

Is this a new strain for you? It could be P def but it's probably just genes. Everything I grow has purple or red on the stems...naturally.

well i have other plants growing as well ,i had 4 clones dat are the same 2 of dem i put to flower after 2 week veg and does are doing good the stem of those are green n healthy lookingg. but the other 2 i left veggin for turned red its on its 4th week of veggin i also have 2 other clones i belive they are lemon kush does are doing real good i water them all da same no difference idk why its like dat i have grown this strain before da pic on my avitar was the mother to my clones

Probably temp differences...I wouldn't worry.

purp purp i likey i always watch the purple stemmed ones the most for some reason

its that purppppppp.


i got stems fulll of purple.
