Impressions about plant
Humidifier set up and working, has increased air temp a degree or two. Nutrient temp is a little higher than I'd like, ~75, and even with Hydroguard, I need to work on that. Yesterday, I added ~4L of ice instead of water to top-up, that lowered the temp from 75 to 70. But the ice, while filtered, isn't as filtered as the water I normally add.
Plant seems to be doing fine. Some lower leaves drying out/falling off, but tops & budlets don't seem disturbed at all.
