Help with trident forest health.

[Pepibom]

Hi there
I currently have a small trident forest whose number one tree just can’t get past looking orangey and a little light colored in the leaves. In fact I wish the other trees’ leaves were darker green. I am in New Orleans so it’s super hot now but I have shading and watering well. I fertilize with bio-gold , mist with Kelp-y water. Other than the arrangement I have going (which needs to be adjusted ) anyone have some advice to get this forest getting and looking healthier?
Thanks!

I see burned leaf tips so my first response would be overfertilisation.
Then again, in heats like that.. Both have similar appearances.
