Yes could be mites. Or some other pest. I would just spray it and watch closely

I had the same thing happen to my meyers leaves when i had them under lights last winter. Never could figure out why they curled like that, but it has been growing normally since the spring.

Could be root stress, salts in your mix, too much fertilizer, unstable temps...What is your tree exposed to? What kind of mix? What kind of fertilizer? Do you acidify your water if pH is too high?

The leaves look very pale telling me something has gone wrong with the mix, roots temps, or the way you fertilize..

In real life the leaves aren’t pale at all. They are quite a healthy, beautiful dark green. If it was a deficiency or a fertilizer problem or Ph issue, then how come:

A) none of my other citrus have this problem?

B) the new leaves are all healthy?

C) there is white grit on the curled leaves?

It looks exactly what happened to my other Meyer lemon when it was over watered and suffered root rot, but this one is still healthy and it’s new growth is flourishing.

looks like scale to me. And striping looks like magnesium deficiency.

If your fertilizer has Mg in it, then the roots are not doing their job for some reason . I would get to the root of that and also spray your tree with a good pesticide..

There r several things u can do 2 kill scale. U can use a systemic which is poured in2 the dirt n absorbed thru the tree. (Chemical n the least desirable but the best results). Take a liquid dish soap ( just a cheap 1). Use 3oz of soap to 1 gallon of water. Saturate the dirt with the soapy water (it will NOT hurt the tree). N spray or mist the leaves with this mixture.

If it's spider mites get it away from all other plants immediately! U'll c tiny spider webs if it's mites. These r HARD 2 get rid of. Put ur tree in the shower once a week 4 a month n watch 4 those webs. If showering ur plant doesn't get rid of them, u may have 2 turn 2 neem oil. This does not kill the mites but it sterilizes them so they can't reproduce. (N they do so quickly).

Now...if u can't win the fight against mites, it's best 2 throw the plant away so it doesn't infect the other plants.

Oh my, for us older members this kind of writing is not easy to read.

Sorry susanne. I am a baby boomer also. Just read it slow. I don't use my thumbs so had 2 find a way 2 make things quicker.

As someone in my mid 30s, that’s rough to read.

I took a q-tip and wipe the front and back of every leaf on all of my trees (minus my key lime) with rubbing alcohol. Then I forcefully sprayed the trees with water. After they dried, I sprayed with been oil. I didn’t find a single other critter and everything looks healthy (except for those few curled leaves). I’m hoping I won’t have a horrendous infestation over the winter.

I was perusing my local nursery yesterday and saw some very sickly citrus trees (only about 8 left from their summer inventory) and visibly bugs. It made me very nervous to bring anything new home. I usually get lots of new house plants, but I’m worried about contamination.

Any oil kills them in time, it smothers them.. Killing the nymphs is key which can take a month...One must be consistent and relentless...Also if one does not like to use the stronger oil and use a product that works just as good, you can always use Safer's Soap. Does it every time without bud of flower loss and without hurting the soft leaf tissue.
