Had this problem, just transplanted into smart pots and hasnt happend since, my guess the heat buildup in pot was effecting them,, anyways just sharing
I transplanted two days ago, watered and then the plants started to sag. Im guessing its a mix of transplant shock and maybe some overwatering. Maybe that is our problem
Don't over treat ur plants u may kill them, some ppl spot little minor things and get worried to quick and then try find something to cure it or fix it by using other chemicals, to much mixer of different feeds or to much over watering often causes plants to die
