perlite has fert in it! forgot to read label.
Just so this doesn't happen to anyone else ...
my perlite that I got at HD (only kind they had...) had fertilizer in it!!! It was MG brand.
Does everyone else already know about this? I was foolish and did not read the package closely. I've never heard of perlite having fert in it. I thought it was a soil amendment. Silly me. Soon they will put it on the table with the salt and pepper.
I only realized *after* I finished a repotting. I hope my plant won't be upset.
