One thing that I have learnt that might help you along your journey is that ideal conditions, are, well, ideal. If you can reach them, that is amazing but not everyone has the money to buy the equipment that you need to keep things at an ideal. Its okay to stray away from certain markers as long as you are paying attention to the possible side effects of them. Look outside, nothing is consistent. These plants are made for rainy conditions, hot and dry windy temperatures. They are resilient.
Just look at your environmental conditions and pay attention to them and the impact they have on your plants. Work from there.
If these spikes are unavoidable, ensure you have something in your arsenal you can use to prevent the side effects that high humidity might have. Keep that mindset going and you will do just fine.
I have overstressed myself about conditions that have very little impact on my grows but what I read on forums should crop ruining. Love and nurture, take care and you will do just fine. Neglect on the other hand and forget about it.
