I was told echeveria lilacina? i'm trying to save her. i know it's probably hard to tell what she is with certainty. she hasn't lost anymore leaves since i got her and put her under my grow lights. also, since she's in plastic (i don't wanna stress by repotting just yet - not until she gets better) i'm watering much more lightly, more often because i don't wanna risk over watering her, soil not drying, etc. and i'm pretty sure that's edema?

Your plant doesn't look overwatered. If your succulent plant leaves are mushy, thats a sign of too much water and should stop watering. Plastic containers shouldn't be a problem, just make sure it has good drainage, you can also try and aerate the soil if the soil is compacted.

You should keep your plant in a dry area, stop watering, and look at the root system for any rot damage. Remove affected leaves, and only keep healthy ones. only re-pot if fungal infection is suspected.
