I have two miltoniopsis divisions that have leaves that are turning white. Any ideas on what the problem might be? They were divided from a larger plant about 4 months ago and are growing in cocnout bark in clear plastic pots that have aeration slots in them. They've been watered every 3-4 under the tap and allowed to drain on the drainboard before placing them back in a southern exposure.
I've tried to upload an image - the jpeg taken with my samsung galaxy is too large? Hard to believe. I also tried to input a link to the verizon cloud copy of the image, but it tells me the format isn't correct - it's just a web address.
