Tiffany, etiolation and watering have nothing to do with each other. One is a light problem and one is a watering problem. Yes, those plants are a little stretchy but that might be fixed by turning the pot once a week or so. There is no sign of rot or damage at the base of the leaves, just the tips. The base of the leaves have adequate water, the tips may not.
But by watering to completion and then waiting until the soil is dry again, instead of watering on a schedule, will fix that too.
Lower older leaves shrivel firs, not the leaf tips. Plant always distributes water among the new growth.
Also, etiolation is caused by growth in lower light levels. Stunning the plant with lower temps and drought does mitigate this.
Its why at times like this underwattering is better done , instead of "water deep when dry at depth"
