I can't figure out what's wrong here, My home is new and the soil is sterile (no organic material so that they can compact it to build on) as all soil around newly constructed homes so I've tried to fertilize well but my BoP plants have dried curled up edges and newly formed leaves have brown splotches and spots in the middle. My King Palms are yellowish green with brown dried tips. I can email pictures to anyone who might be able to help but I don't know how to post them with this message.
Thanks

I would try adding some organic humus to the area surrounding the trees, to give the roots something to feed on. Also, try some superthrive regularly during waterings. It has tons of nutrients and will help all and any plant live in the vicinity.
