This is  one of  two  Socratea Exorrhiza seedling that I have and they basically have the same growing conditions-- same soil, watering and sunlight position.

This one though is suddenly turned into a Dalmatian.  No signs of anything wrong 2 days ago.

The only big change I can think of is that its been getting hotter here and yesterday was a clear day so this might have gotten some intense sun exposure.  That new leaf is freshly opened and I am thinking that its a bit more tender.  The other seedling's leaf opened a lot earlier and must have "hardened off" earlier.  

But then again I don't think that sun burn comes in Polkadot patterns-- right???

I am just theorizing here.  Anyone out there know for sure what going on with this seedling?  Should I be worried?  How do I fix it?

That's what I was thinking, scale. Maybe it's a fungus?? Might be a good idea to give them a dose of fungicide.

Gene,

I am no plant health expert.  But, my socratea is a nice green color with no light colored leaves.  It is a little older and I did not grow it from seed.  I pulled it up in the forest and brought it home.  It now is putting out new stilt roots and is looking pretty good.   They do grow in shaded areas in the forest  for the most part even when mature.  Although there are a few close to my house that are in full sun in a little patch of urban forest. The are not an emergent tree.  

Here is my little one.

Lucky you, Don... I wish I could go to the bush and dig up socratea, or mauritia flexuosa (I have been trying to find those 2 - haven't got any yet   :( ). All we've got here is seedling of carpies!! I just found 3 in the block that Scott is trying to hide from me. He knows I hate carpies.

Regards, Ari :)

How can you hate carpies Ari after all they've done for you  ???

I think the spots are from a bug but I'm not certain, sorry.

Happy Gardening

Well for now based on the comments I'll just move them to a shadier place and douse the soil and the plants with a fungicide.

I tend to think this is a Bipolaris type spot because of the halo effect around the dead bits, while a fungicide program would be helpful it is also important to lower humidity, maintain good hygiene and reduce spore from other plants

Can anyone elaborate on the Bipolaris fungus and whats the best way to treat it?  How does it spread/infect?

Gene, you may have seen my melt down with these earlier...  I think I killed about 75 percent of my crop due to sunburn...  If I had to take a guess at your plant based off the photograph I would say you have 2 issues affecting this baby.  1.) everyone has mentioned it already, too much sun.  I think that is why the leaves look bleached.  2.)I would bet dimes to dollars that the spotting is from soil that isn't well enough drained.  I'm loking at the containers in the photo and some have different soil composition that this S. exhor...  

I'd put this baby in shade to deep shade and either water less or use a faster draining medium...

Ive done everything thats been suggested so far.  Good thing is that there is a nea leaf forming already to

The spots are getting bigger though.

Since this spotting is only on one leaf,  suggesting that it is a localized problem----  Shouldn't I just cut the leaf off?
