Hi I need some help identifying the cause of this issue. 90% of the leaves on the plant appear deep green and healthy with no abnormalities at all, but there are a couple of spots where they appear to have some issue in that they are yellow/browning, and in some places completely charred. A couple of leaves this seems to start right in the middle of the leaf, and in others it's starting at the edges. Would this be a nutrient burn of some sort? I've been watering her weekly with 30-10-10 and she's under CFLs most of the time, and I monitor constantly so they lights have never been in contact. Any experts have any thoughts? For now I'm going with a water flush.
