Don't be discouraged we will find out an answer. My first thought is they may have been too wet. They need to dry out somewhat between storms - they are from dry climates. Try covering them if you get too much rain.

Also, my date palms started turning yellowish and required a sprinkle of epson salts - date palms need magnesium.

i agree with brooklyn- CIDP's dont like it too wet or to humid... they will rot from the bottom up. they like it more dry and hot or warm. even as seedlings they don't need full sun but im not exactally sure any pics may help. good luck tho. -Justin in VB

Ditto the above posters. Most Phoenix species have an issue with very high humidity and constant wetness. That's because many of them originate in semi-arid or Mediterranean climates where humidity levels are not sustained at high levels (the Canary Islands are rather dry remember). I once received a CIDP from S. Florida and it was covered in these ugly black spots. I figured at the time it was related to the humid climate and didn't make an issue out of it. Sure enough, it grew into normal growth and is now gorgeous. The discoloration you're experiencing won't revert to normal, but new growth will be more normal once your humidity levels drop. Good luck!

sorry my computer lagged or something and posted 2 times and i dont know why hours later haha. anyways yes njoasis i def. agree with you the black spots on the date palms as u said are from high humidity too much constant tropical heat... they can take some for a little but not long. Very nice story tho NJoasis.

I agree they are desert palms and like hot dry conditions. If possible I would move the survivors out of the rain when possible.

Thanks. I will move them under a covered porch and see what happens.

When it is not raining, give them as much direct sun as possible. The flip side of being a desert palm is they need as much bright sun as possible.

good luck,
