Yellow outline on leaves

Gringo420 · #1 (**permalink**) 07-17-2009, 06:13 AM

Hi, I have a problem im having trouble figuring out or finding any information on. On my plants I am getting a bright yellow outline around the leaves, especially the newer ones near the top. Unlike most peoples problems im seeing with yellowness mine is different in two ways. 1. Its just around the outline of the leaves, the centers are green still. 2. The yellow doesnt look like its drying or dying. It looks perfectly healthy other than the discoloration.

Im including a couple pics of the leaves. Any help or feedback is greatly appreciated.

Is your light to close? It is only affecting the top of

plant? Looks like heat burn or bleaching.

Well it is mostly towards the tops of the plants thats the problem area. I will try backing the lights off a bit since this is the only idea so far. Still interested in more opinions though.

Looks like light bleaching and they're heat stressed. The leaf edges are curling up.
