Great. They look MUCH happier now.
If you have a sec, go through and remove all leaves that are dead and dying for 2 reasons:
-Dead leaves sitting around attract pests and fungus yuck
-This will give you a starting point of reference to see if there is any more die-off since you have changed your procedure. If not, that was your issue. If you see any more problems, you still have some tweaking to do.
