Hi Dan, You're gonna need to get more info up here, what I see looks like the soil is wet and compact. If they were mine I would repot into three or five gal. smart pots, using a good potting soil and about 25 or 30% perlite. Ph the water to 6.0 keep the temps under 85 and make sure there's some air movement. Allow the soil to dry out some before watering again.
