You should be good on the rot and mold. Your buds are growing apart and you have plenty of air flow through the actual buds.. Check out the rot I got. My colas were way more dense and I'm outdoors. We had high heat and humidity for months. The rain for days ie 100% humidity
I lost 2 terminal buds but my 3rd plant is more airy like yours and I got that shit under control. No more rot, but my humidity dropped to 60% and high pressure system has been around keeping it fairly dry and cool and breezy.
Blast them with a fan mold and rot hate dry, wind and light so give them plenty
let them grow sideways to then the buds will go up away from the stalk instead of into each other.
