ah the water spots totally explains it!

i know i have seen them with big drops of water on the leafs after watering them and i didn;t really think much of it to get that off... but now that you mention that, i realize the drops of water was focus'ing the light like a magnifying glass and burned a hole in them! oops! probably happened when i took them out of the cab and put them on the inside of the patio door to catch some intense afternoon sun... i hope they'll forgive me
