depends on what caused it - heat, cold, or sun exposure. Hard to picture window light causing wilting so was it especially hot out or cold? Heat vent blowing on them? Any chance they are rootbound and just dried out?

well i watered them on the 27 and its been 80f outside so its been hot.no heat blowing on them just the heat from the sun, they were dried on top of the soil and i watered them 2 days ago so i thought that they would be still moist further down in the soil.

These are different sized plants. Are they in the same sized containers? if so then bigger plants will dry out much faster than smaller ones. The size of the root mass in the container is as much different as the mass of the top growth is so their water needs will be very different.

If the larger plants perked back up once you watered them then you have your answer as to the cause. Sounds like it might be time to transplant the larger plants into larger containers.

there all in the same sized container and they did come back up after i watered them.will transplant them to bigger containers. thanks
