What does this mean? This is my first time around growing, and I'm growing from seeds, I got the seeds from a friend who said they got them online, and that they were White Widow and OG Kush. They had them all in one bag so I'm not sure if they were a cross or separate Plants, also fem from what they told me. Regardless, I have one plant growing in my closet, from seed. Germd, then went into Fox farm ocean forest, I know some people say seedling can't handle it, but I didn't know. Worked out good for me. She's under four 23w daylight cfls on 24 since I planted, and two fluorescent fish lights, unsure of the wattage. I water a day after I notice the soil is dry, and she seems to enjoy the dry periods. I haven't used any nutrients yet, because I can't afford the grow big and bloom big I want. >.< I should be getting some soon. She's in a three gallon pot now, and she's just under a foot tall I topped her, and tied her down for LST/bonsai train which is working out well as far as I can tell. She has this nice purple colors in her main stalk and on the stems of the leaves. I was wondering what this means if anything. Also and input on improving my set up is always appreciated. I want to build a cab sometime soon. I'll post some recent pictures when I get back home. I don't think I can do it from my phone.
Its nothing to worry about, most healthy plants will have a bit of reddish purple color in the stems when you look at them under Fluroescent lights beause they put off light in a more blue spectrum....its not as noticable under HPS or MH because they run with a more yellow/ orange spectrum of light and the purpleish color (even though its there) is barely visible under that light spectrum.
Red or reddish stems are a common and normal trait. They do not mean your plant is ill, as I have heard people say here and elsewhere. It means absolutely nothing unless you like red then enjoy.
