Welcome BooBeats Thanks for sharing pics of your current indoor GT grow, plenty of Thai influence in your 4 individuals are you growing the regular or the feminized version ?
Sorry to hear about the pm, it can be a real trouble, especially with the longer flowering sativas. You will need to clean every tool and garden surfaces with bleach to make sure you have killed all the nasty spores from your indoor grow room. If the pm problem show again after the cleaning and after start the grow from scratch then it's due to the grow room was not fully disinfected. If the problem persists and you cannot fully disinfect the grow room then you may need to use systemic fungicide.
