The tips look like nitrogen toxicity, which you already corrected apparently. If it stops spreading, you're good. Those small yellow spots could be just about a million things, but I would try to solve that one unless it starts spreading. Keep it up!

Hey mate, I'm sure she'll take it like a champ. Happened to me many times, just keep the node tight up and you'll see in a week to 10 days it should be fully healed. Good luck and happy trails for the rest of the way 🤞 Servus✌️ OimRausch

Then you're probably good.. It would be best if you could humidity down to 40 - 45% tops, but with good airflow 55% isn't the worst.

First, a change of smell alone may not be mold, but you'll want to look them over for symptoms... check out google images for some examples and go to work. you've probably smelled a moldy room before... if it has hints of that, it's not a great sign but i'd still observe for 100% verfication before doing anything crazy.. Those aren't dangerous levels for microbial growth. The night time humidity is a bit inviting but borderline. You may be colonized and need a deep clean of the area and the room, especially if you have a recorring problem. If you do find some rot, definitely decontaminate the area thoroughly before next grow. Try cutting out any rot and carefully removing, like you would with a pollen sac -- with concern about spread.
