Hi all, Just picked up a nice mature philodendron selloum hope from the garden centre and was wondering if any one could help with a question? I know these can suffer from yellow leaves if they are either nutrient deficient or have been kept in to bright a condition. A quick Google shows a lot of these plants have yellowing leaves, so I'm trying to figure out if I need to do anything to get it green again. The top leaves are the most effected which is why I thought to much sun to begin with but the lower leaves are also a little yellow. It does have some burn marks to the leaves as well but not completely sure if this is just a coincidence hiding a nutrient problem. Most of the leaves are just a slight yellow like this, size 11's for scale But a few leaves are like this which I think might mean a magnesium deficiency? At least somewhere in the back of my mind I remember yellow v marks being a mag problem in philodendron Either way it was a very cheap price for such a large vigourously grwoing plant, so even if I have to trim the poor leaves of its still a bargain. Thanks in advance.
