i was growing some pawpaw seedlings hydroponically last year and come fall i was going to bring them in and see how they do overwintering in the tent. they had some transition time in the garage before they went in the tent. it never froze but it did get pretty cool a few nights when they were in there over a few weeks.
once i got them into the tent i noticed that they started showing signs of what looked like brunt leaves even though they were under other plants canopy. so i moved them out of the tent as it kept getting worse. eventually one by one they started losing their leaves in what looked like a nutrient deficiency.
i think there might have actually been some burning going on but what i really think was happen is they were just going dormant. there is a single leaf holding on to one of the plants at this point. they all are still green under the bark and have small fuzzy buds. i dont see any root expansion at all though.
do yall think they just went dormant and how does their dormancy period work? are they on a timer of months on when to wake up? the temps are ~75F during the day and ~65 at night with ~16h light(they are still under canopy). you would think those temps would have woken them right back up
