@Bostongirl17 indeed my temps are varying right now... Lowest at 21.7 Celsius, highest at 26.5 Celsius, this could justify purple stems maybe. Thanks for the input! I'll keep an eye on her for those marks and signs of pests/funghi, my grow room tends to have high RH, pretty difficult to control it here, I'm only managing to get RH to 60~65%, 55% lowest.
