Help identifying problem

  1. One of the older big leaves on one of my plants look like this. What are some causes?

    They were transplanted one week ago with Fox Farms Ocean Forest in 2 gallon pots, no added nutrients, 6 23W CFL's shared by 2 plants, temps stay below 80. I'm watering with bottled water. And some of the tips on the other leaves are a little dark.

    I'd appreciate any info.

  2. After some research it looks like it could be a Mg deficiency, Any thoughts?
  3. If that's one of the first leaves that grew on the plant, it could be just a natural "dying off". As long as all of the newer emerging growth is fresh and healthy, it shouldn't be a problem. Generally speaking, MJ plants don't require supplemental Magnesium until much later, usually when flowering. Additionally, your FFOF soil should have the nutes required for the first few weeks.

  4. Yeah it's one of the first leaves. The rest looks healthy, it's only that one. Should I leave it alone, cut it off once it completely dies,...?
