Young coconuts deficiency ID

[LF-TX]

Hello everyone,

Could anyone tell me why my coconuts have these leaf problems? It’s been going on for about a month or two already and the browning/yellowing occurs very very slowly but it happens. This along with the brown spotting. 

I’m really clueless as to what could be causing this.

Any feedback and suggestions on how to reverse this would be greatly appreciated.

Is the soil constantly wet and cool?

That seems like a larger than needed pot? My coconut did that because of too wet soil and too cold of conditions

I do water often, and really it has been pretty cold this past winter. They’ve spent a considerable amount of time in the cold this past winter.

Looks like classic cold damage. Once the heat and humidity become consistent they'll grow out of it.

I agree, cold damage.

Def do not water frequently when soils cool. Our dry season in Florida runs Nov-May. I rarely water my coconut in the ground and potted plants only when soil is dry. I have heard soil temps of 62F and higher are needed to keep cocos from stressing. My soil temps in winter fluctuate between 63F and 67F with spikes lower and higher. Once they hit 80+ is when the growth really picks up. Spear growth then is about an inch or so per day. Good luck and keep us posted!

That looks to me like a Fungus. Do you water your coconut fronds or just the soil?
