yeah np pbp its really not that difficult at all its just sometimes when conditions suddenly change it can throw things out of whack with the plant.
so dont be discouraged these things happen even to the best of us
when the conditions change drastically, or something else out of the ordinary happens to the plant, it then becomes a balancing act(thus making it sometimes so much more complicated) to make sure
all things (versus just watering and feeding the dang thing lol)are going along okay with the plant.
However, youve gotten this far, and done a pretty damn good job considering what the plant has gone through, heat stress, multiple transplants, nute burn etc....
So with that being said gardening is always a learning process even for those who are extremely knowledgeable. Personally, my view is always no matter how much one knows about gardening, one can still learn something new each day and that includes myself as well
Enjoy the grow and have fun
and +rep for getting your plant through those conditions as some artards (not you of course)out there will just let their plant die and not care for it as much as you seem to so keep it up and see her all the way through and she'll definitely reward you for all your efforts in taking care of her
