I am in week 3 of vegging and i had a slight problem and just got it fixed and it is now growing like crazy. when it had the problem (either ph or nutrient not sure which one) the main stem and some fan leaf branches turned a purplish red color, when it started growing again, the new portion of the main stim is now a nice healthy green, but some of the fan leaf stems are now turning that color and some of the leafs have like a little bit of purplish look around the edges, the temp in my closet where the plant is, is about 75 degrees so its not to cold. i will attach pics later sorry for the massive run on sentence lol
have u been feeding it and if so what? you should feed it something every week or at least every other week and perhaps it got to cold one night. it could just be the way they are. if you had pics up maybe someone could help u more.
