Tropicals & Tender Perennials: Fertilizer advice, please!, 0 by markroy68

Some of my Hoyas are showing a strange new growth defect. I've allready posted a picture of some new SBI-1 leaves which had strange mottled colors on the new growth, as well as some stunted growth in portions of the leaves. It was suggested by Carol that it was a nutrient dediciency, and I think that is probably right, but would like some advice on fertilizing regimens and type. I grow in 50/50 peat and perlite. The perlite has no nutrients to my knowledge, I don't know about the peat. I had used epiphytes delight, since this is a very light mix and I was not sure a regular fertilizer would break down properly for plant use. I had fertilized every three weeks or so at half strength. Some plants, such as carnosa types and australis (the more vigorous maybe?) seemed to be just fine with this, but SBI-1 still looks weird and now H. campanulata has the same defect, although no strange coloration. I think I'll switch to schultz 10-15-10 at half strength at every watering, for the time being. Input please!
