Same spot on an outdoor plant I have but I know that mine was caused by the temp dropping down to 0 the other night. Fricking middle of june and weather going down to frickin freezing. Global chilling. That will be the new tax grab...

Newbie:Now in three weeks: the lower leaves start to turn yellow quite fast and it is moving to the leaves above it already. One disformed leave as well. Growth seems to slow down a bit. This is fresh fertilised potting soil and I am pretty sure I am not overwatering. Any ideas?
