Over fertilization of potted Carpoxlon with seaweed foliar

[SWFLchris]

I did a seaweed foliar spray to all of my small potted palm seedlings yesterday. I immediately noticed these yellow spots on a few of my Dypsis and the worst showing on this Carpoxylon Macrospermum. 

Is this a result of too many nutrients? That was my second round of foliar spray. I did the first one about three weeks ago. I am thinking I may the solution too strong.

A little background info, I just recently got the palm bug and I am obsessed! This is my first post...

If you apply too much concentrated foliar spray it will cause damage. Hopefully someone can correct me if I am wrong, but I would spray the palm with fresh water to help remove the excess nutrients from the leaves.

Foliar sprayed nutrients are minimally effective. Rinse off the residue. I suggest next time you dilute (if required - read and understand the dilution ratios - stronger isn't better) and use the seaweed as a soil drench. Wait until spring before attempting to fertilize again. I never fertilize after Nov. or before March. Very young Carpoxylon can be tricky, as I found out to my woe. I grew my surviving palm in pots for 3-4 years before planting it.

Thanks for the info and the welcome, it is much appreciated. 

How is your Carpoxylon doing today? Was it planted pre-2010?

I planted a large 7-gal in my moms yard in Clearwater early this year, I am worried about this first winter being bad.

Doing great. Planted as ~7g in 2012 in my south-facing backyard jungle above the canal. Gets filtered sun most of the year. Young ones have problems with full FL sun. Photo below is from Oct. 2016. It has several inches of trunk now. As long as yours is in a pot you don't have to worry too much about winter. Take it indoors when/if nights fall below 40F. I protected mine for a couple years after planting by wrapping it in a blanket until it grew too large. I trolled thrift shops for cotton flannel sheets or blankets and pillow cases to cover small cold sensitive plants. I've been known to pull out all my towels or dress my palms in jackets, hoodies and t-shirts to protect them from cold or frost. Except now, most everything is too large to protect, except for a few rare coconut seedlings.

Beautiful palm! Nice work and thanks for the reply
