Super Silver Haze Autoflower

Wow, the ladies continue to fatten up nicely. I gave them a trim to expose lower bud sites and she responded! They have been soaking up the PH water and I can tell they are more thirsty now with massive bud growth. I placed a small space heater in grow room and think the plants definitely like the warmer mid 70’s versus the upper 60’s, buds getting more dense and much more sticky. Very frosty. About 25% of hairs have turned brown and monitoring daily. Once it gets to approximately 75% brown pistils, I will start to keep an eye on trichomes. Still trying new things to find my grow rhythm, but happy with results. I like how buds are so tight and attribute it to better defoliation which enables better light penetration. Still new at this, so what am I missing? Any tips or tricks you could give a new grower are also greatly appreciated. Cheers!
