Arash I would unpot and check the roots, mealies on top can mean mealies on bottom too. I agree with Rick that 6 to 10 weeks of age a bigger pot could prove fatal. It may prove useful to post some pictures here so we can see exactly what we are talking about.

I may be wrong about them being 6-10 weeks old, thats what the daughter of the nursery owner told me. Below are pictures per your request/

The mealy bugs are in the 2 pictures below:

And this is how large they are (4 in pots):

Those are bit older than 6 to 10 weeks. I would still stay in the 4 to 6 inch range for pots, any bigger could be fatal since the media cannot dry fast enough. If they were my plants I would cut off the affected leaves, wash the plant under warm water thoroughly and treat with an agent and repot into clean media. Separate or quarantine from your healthy plants so the disease doesn't spread. Keep us posted on the progress Arash. Good luck to you, they are nice little plants.

Thank you Tracy! I was planning on either transporting into fresh 4in pots or 6in pots.

But I am definitely changing the medium. I have a 50/50 coco coir/perlite mix as well as a buddy is dropping off some Al's gritty mix. Given the age of these little guys, which medium would you think is best?

Thanks Tracy :)

I would definitely agree with Tracy. Stay with 4" and not bigger than 6" pots.

The soil they are in now looks a bit green on the surface, good that you are replacing.

Might be worth adding something like Pine bark (small) or Coconut husk chunks along with what you are going to go with. It will add more drainage and aeration to the soil.
