You are correct - these plants like relatively low light. While they do not like to be soggy - this specific cultivar doesn't require to dry up - I keep it successfully on wick and mat - provided that the soil is light with a hefty amount of perlite. So - my suggestion - move it to a northern window and do not let it go too dry. Regarding the second issue - wobbly. I think it is a consequence of a too hot-too dry-too bright. The plant is not developing a good root system. Plant it deeper - may be you will need to remove older leaves - and stake it with bamboo skewers so it is looking up until it develops enough roots.

Regarding the wilty leaves... wrap it for the night in a wet paper towel, it will help to rehydrate the leaves. In nature Primulinas grow at the entrances of the limestone caves on the shady side of the hills. The limestone is like a sponge - after the rain it slowly releases the water - so the plants have a source of water and ambient humidity all year around. Even it didn't rain for a while - the soil in the crevices never goes bone dry - and it is never soggy - the water runs down... BTW - adding a pinch of dolomite or crashed egg shells is good.

The good part about Aiko - it is a cast iron plant, it will survive.

Thank you for your advice :) I actually did stake it so it doesn't move, even if my sister moves the pot. So Keiko likes to stay a bit moist? I heard that primulinas like the soil a bit drier, so I've been letting them dry quite a bit between waterings. Seems to be working for Aiko, but I'll try keeping Keiko a little wetter. Fall should be coming soon here, so maybe the cooler temperatures and lower light levels will help it perk back up. I'll move it to a shadier window. The moisture does explain a lot, though. I couldn't figure out why my buds were blasting. Guess it was too dry to support them

Keiko is similar to AIko in culture. I know a couple of species that require your kind of treatment. Primulina minutimaculata will absolutely rot if kept wet. P. wentsaii requires high light and dryer conditions to be spectacular
