It's a form of mold from over watering. Scrape it off and let your medium dry up more before watering.

Truth to giving the roots a reason to grow?
In dwc I have seen different opinions on water level. Theres a saying that lowering the water to gives the roots a reason to grow but shouldn't the roots be saturated? I'm day 31 and I have the water just below where the rockwool would be and roots look awesome.

Is it safe to tweak your light cycle times when you flip?
I'm getting ready to flip and was hoping to adjust the cycle time when I do. My light is currently on from midnight to 6pm, but would like to switch to 9am-9pm or 11am-11pm to better align with my schedule. Am I safe to adjust or should I keep it at 12am-12pm when I flip? Thanks!

Harvest time
How much until harvest? I’m 9th week of flowering, she’s getting some burn but the thricomes are still not turning to amber. I don’t have a better macro lens, so can’t give higher magnification. She is photoperiod, changed to 12-12 like 11 weeks ago.

Pollination question! Help please!
I have two tents side by side. Both have inline fans installed with filters. 6 female plants, 1 male, how likely is it for pollen to wind up in with my girls if I keep the male in a separate grow tent? I want to selectively pollinate branches so I still have good bud too.

Is this the 'amber' I should be looking for? First grow here.
I don't want to chop her too soon. I've had issues my entire grow, and I don't want to assume anything anymore.
