white paste on TOP of mandarin leaves
I saw posts for white stuff on the underside of leaves but this stuff is on top of the leaves on my plant. I've tried googling it but can seem to find out what it is there no scales and it doesn't appear to be an aphid. also a couple of leaves with what appear to be on or two sprinkles of pepper. I noticed the pepper sprinkles about a week ago and now this goop appeared this morning. was not there yesterday. also new leaves are growing but the ends turn black and wilt away. its a young tree so I don't know if it is supposed to have fruit yet but I noticed very tiny balls of what I thought would have grown into fruit but are brown and dried out. please help.
ps there were three leaves affected by the white stuff, I cut them off and after taking a photo I burned them in case it was some sort of egg as I didn't want it to spread. I also have a 7 foot lemon tree but I don't think it's affected yet.
