I'm 9 weeks from germination. Using Coast of Maine soil and General Hydroponics Flora Trio for nutes. Humidity is at 65-70% temp is around 68F. Using Mars Hydro TS600 for lighting.. Main bend is from LST. Am I on the right track? Buds haven't really changed in the past 2 weeks and some pistols are turning orange/brown.

The temperature when the grow light is on is 68F right? Ideal leaf surface temp is about 82F so if you can bring your environment's temp up a bit that should help with growth. How far away is your grow light from the top of the plant?
