This is definitely a case of too much everything. Second pic shows N toxicity, very dark green leaves. Looking at the diary the other plant is showing signs of magnesium and possibly calcium. I would just give them clean pH 6.5 water with some beneficial bacteria and humic acids, small dose of calmag for at least two weeks. Try and help her recover from the stress. Lift your light up 6 inches and see how she responds. I hope this helps in some way, good luck
