Hey friend,
So firstly it's not as bad as you might think. You're doing a good job so far. But looking at your diary i would suggest raising the ph a bit if possible, maybe some homemade humidity domes if they'll fit. Also this week it says your night temp is in the 50s was that a mistype? If not you really need to raise the temp...anything around 60 gets risk of botrytis etc.
The leaves drooping makes me think they're either under watered or over watered. The next time you water see if the leaves perk up and straighten out.
Good luck with the grow and slowly working out the kinks. It's definitely an exciting and frustrating process.✌️
