Archontophoenix purpurea seedling damage?

[markincorpus]

Hello again folks.  I am hoping to find out why my Archontophoenix purpurea seedlings are showing damage while my Archontophoenix alexandae seedlings look great.  They are under the same shaded conditions and being watered the same.  Can anyone help with what the problem may be?

Here is a comparison of Archontophoenix purpurea and Archontophoenix alexandrae.

Could it be that the 'purpea' seedlings are more sensitive to the pH of the potting soil? Just a stab in the dark.

Too much water?

I have four and I still have to figure out how to keep them looking their best. By reducing the water now they all put out leaves without shriveling. Now I gotta figure out how to make them look greener. I recently moved my best looking one to acclimatise it to more sun and it wasn't long before it started getting sunburns. This one is not for the beginner!

I thought about this as well....but strange since they are from a swampy area. Is the water being used 'hard' or 'soft' water? That may be the ticket.

"This one is not for the beginner! "

Well I am definitely a beginner so wish me luck.  I am going to try reducing the waterings since I have been extremely generous with the watering during this hot weather.  I'll look into the hardness of the water too.  Is there an easy way to do this? Thanks everyone for the responses!

My guess is the soil. I would repot it in a smaller pot with new soil.
