Stem, underside of leaves turn purple on sprout.. normal?

[jrk152]

Woke up today to find my 6 day old sprout had its stem and the underside of the leaves (top of leaves are green and good) turn purple! Strain is unknown, temps are 75-85 and humidity between 30 and 35%. Is this normal?

Pics 1 and 2 show the seedling today, pic 3 is from 2 days ago when it was all green, for comparison.

my guess is genetics.. or you have it too cold when the lights are off/on

i thinks its normal bro....my plant had the same thing happen though the strain is purple kush so maybe ur growing a purple plant.......my friend has about 6 skunk plants and 2 afghans and they all at one point had purple leaf stems. my kush plant the leaf stem is only purple on the bottom now and the top of the stem that faces the light is green....

I'm on 24/0 at the moment, no night time for my (hopefully) girls.

Its most probably a skunk variety as that tends to be what we get around here.

ok cool one thing you can do is look up nitrogen deficiancies and potassium and phosphorus and see what the signs of a marijuana plant lacking anyone of those are.....ive heard that a lack in one of those can cause purple leaf stems....

I think it's the genetics. If it starts dying then you have a problem.
