Wash cucumbers well with cold water. Trim blossom ends and cut lengthwise into 1/4-inch thick slices (4 inches long). Place slices in large bowl with turmeric. Pour boiling water over cucumbers; stir well. Let stand at room temperature 3 hours; drain. Rinse and drain again.
Place 1/2 tablespoon dill seed, 1 teaspoon each dill weed and mustard seed, 1/4 teaspoon minced garlic, and 1/8 teaspoon crushed red pepper in each of 4 hot sterilized wide-mouth pint canning jars. Pack cucumber slices vertically into jars.
Mix remaining ingredients in medium saucepan. Bring to boil on medium-high heat, stirring to dissolve salt and sugar. Ladle over cucumbers, leaving 1/4-inch headspace. Cool. Cover jars with metal lids and screw on bands.
Refrigerate pickles. Shake jars once a day for 7 to 10 days to redistribute seasonings and blend flavors. Store in refrigerator up to 2 months.
