Aloha all,

I have what I believe is some type of Tabernaemontana (not sure which one) that is looking very poorly. It has been turning white between the veins for ages now, mostly on the newer leaves. So far I have given it Miracle Gro 24-8-16, Bloom Booster 15-30-15, epsom salts in H2O, Chelated Iron with Zinc, fish fertilizer, Alaska seaweed extract 0-10-10 over the past months. Nothing seems to be helping it - any thoughts?
