Not a real problem, some strains naturally have red stems, especially when flowering and it won't effect yields or potency, so nothing to be worried about, it is not a serious issue in the least and can be ignored, your plant will be A OK. Cheers, Organoman.

Need better pics. Could be genetics. if not.....If the plant is healthy its strong light intensity. If that's the only issue its nothing to worry about.👊

Early growth sick plants - photoperiod Purpling stem, yellowing leaves, droopy leaves - I’m thinking nitrogen deficiency, but I’m not sure if I should add more nutrients or not to my current solution or if I should flush completely. PPM is at 850, and the PH is 6.3. What are your thoughts? Any GH nutrient schedules?

Spots on leafs, and lime green tops I am beginning to see leaf damage again, so i would like to ask if you guys could point me in the direction of my problem. I suspect either light damage, or ph issues building up over time. It started before i gave the first flower nutes, tops seem deeper green since that though

New red tint on top of branches caused by night of low humidity or other stress?This morning I noticed some branches on my young plants had turned reddish on top. Last night the humidifier ran out of water and RH dropped to 40% overnight. Could this just be a stress reaction to that low RH, or sign of a deeper issue?
