its been very warm-- even today -- could it have dried out, even the wind will have a drying effect without sun

If by a planter you mean a pot or trough, Kenny, these can dry out surprisingly fast in warm weather, and rain rarely does a thorough job of watering them. I would check them for moisture every day, at least until you get a better idea of their rhythms, and water if needed. The idea is to water them before they wilt, as wilting does damage every time it happens. If they don't perk up after wilting, then look for other problems, such as soil insects, bad drainage, or root rot.

Many thanks for that. Gave it a good watering last night and typically its pouring down today. Jas seems to have perked up a lot and i'm hoping it stays that way. Again, many thanks...
