Titanium and aluminum are often used as colorants in tattoos; more worrisome, inks using nonmetal colorants may include traces of antimony, arsenic, beryllium, chromium, cobalt, lead, nickel, and selenium (AESI filed over the latter eight metals).
Apply about two ounces of a 5-10-5 fertilizer around each plant. Starting the second season and annually thereafter, fertilize raspberries in early spring before growth begins. Apply a balanced fertilizer, such as a 10-10-10, at a rate of 15 to 20 pounds of fertilizer per 1,000 square feet of planting. If using the hill system, apply about one-half cup per plant. Don't fertilize raspberries in late summer or early fall as it may force new growth that does not harden off properly for winter.
For the raspberries I just use 10-10-10 just when they start pushing new growth...maybe somebody else will have more suggestions. For the blueberries the advice to wait a year is wrong. What you want to do is fertilize them monthly or even weekly but with very very small amounts. Find some ammonium sulfate and use 1/2 tsp per gallon weekly and after a month or so switch to 1 tsp per gallon of water weekly. Just make sure when you fertilize them they are not dry.
