stem turning red??

see the top and bottom little stems are turning reddish almost brown.. anyone know if this is bad or just genetics?

The rest of the plant looks fantastic so its prob just genes. How many weeks are they along?

we are looking at a day shy of 3 weeks into flowering with cfl's its my first grow and they are looking very good to me my cat got into my closet the other day.. and luckily i cought her because my plants would be destroyed but she ate like 5 leaves all together and my cat seriously slept like a good 18 hours

Genetics. If it was a nutrent issue you would have other symtoms as well.

Nice plant.

LOL that's funny as hell! ... Err ** Sorry for the plants, but... ya gotta admit the 18 hours of crash your cat got is kinda funny.

ive worked at an animal hospital for years and ive seen dogs and cats come in that have eated bud or brownies or somethin so fucked up they cant even drink. lol plants lookin healthy where she bit em off so im not too concerned
