Listen UP!
Well first if you:
Flush the Bitch...Pour copious amounts of water through and through... maybe take her into the shower with you....
Then Buy yourself a PH tester... and test the PH of your soil....
---------------
^^^^ No... your best bet... would be to start over...
I would take it as a challenge to save your plant...
Add potting seedling mix to stem 2-3" up to top...
Then prop up your leaf on Edge of cup...
I'd move a CFL within inches...
Holes to drain bottom of cup?
I feel so sad...
Another bites the dust...
