From: Jill Bell godjillab at home.com> on 2001.12.16 at 22:11:37(7926) Hi Derek, The interesting thing is they are NOT stealing from the old leaves. It is the new growth which is effected, I put the images on my website so you can look if you would like. I am sure that I need magnesium because I have never known that aroids had such a need for it before, so I will get some. But I wish you would look, and you can click on them for a much LARGER look. (Scott said that you and he would be looking with magnifying glasses) But this is the best I can do for now. I really appreciate the support and your knowledge and I have no doubt that you will be able to help me solve this. I have spent the morning repotting the damaged ones, washing off roots to hopefully get rid of any built up anything that might be on them. So, I will get the mag this week and I do fertilize with 20-20-20 regularly, so shouldn't that take care of the potassium? Or do I still need more? the above is the link for the images.
