  1. Hi all,
       I've got a couple of pineapple clones in coco that are a month into veg, just flipped to 12/12. Some of the leaves have holes appearing between the veins, new growth and old are both affected. I cannot find any pests with magnification. The plants are otherwise very healthy and vigorous. I've searched every forum and source of info I can find but no answers have been found. I've found a few other people out there with the same problem and no one seemed able to answer them either. I should add that I've found a few water droplets on leaves despite the fact that I have not gotten any water on them. Here are some photos: 
       Any ideas?
       Thanks.

  2. A couple of the pics show what the leaves look like before the holes develop, kind of thin or worn looking between the veins.
     
  3. I'm stumped on this.... I can't find any answers anywhere. Anyone?
     
  4. Mag deficiency, probably from a low Ph. I had this problem trying to run a constant 5.5Ph in hydro.
