I have 3 different ores I am trying to have only spawn in a certain stone variant each. I have set up predicates for each stone variant, the ores are spawning but in all variants of stone

 

this is my OreGen class:

package hazmatik.sonictech.worldgen;

import java.util.Random;

import hazmatik.sonictech.blocks.BlockAntimonyOre;
import hazmatik.sonictech.init.ModBlocks;
import net.minecraft.block.Block;
import net.minecraft.block.BlockStone;
import net.minecraft.block.state.IBlockState;
import net.minecraft.block.state.pattern.BlockMatcher;
import net.minecraft.block.state.pattern.BlockStateMatcher;
import net.minecraft.init.Blocks;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkGenerator;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import net.minecraft.world.gen.feature.WorldGenerator;
import net.minecraftforge.fml.common.IWorldGenerator;

public class OreGen implements IWorldGenerator {
	
	private WorldGenerator antimony_ore;
	private WorldGenerator chromite_ore;
	private WorldGenerator copper_ore;
	private WorldGenerator molybdenum_ore;
	private WorldGenerator tin_ore;
	private WorldGenerator zinc_ore;
	
	public OreGen() {
		antimony_ore = new WorldGenMinable(ModBlocks.oreAntimony.getDefaultState(), 8, new DioritePredicate());
		chromite_ore = new WorldGenMinable(ModBlocks.oreChromite.getDefaultState(), 4, new NetherPredicate());
		copper_ore = new WorldGenMinable(ModBlocks.oreCopper.getDefaultState(), 6);
		molybdenum_ore = new WorldGenMinable(ModBlocks.oreMolybdenum.getDefaultState(), 8, new GranitePredicate());
		tin_ore = new WorldGenMinable(ModBlocks.oreTin.getDefaultState(), 6);
		zinc_ore= new WorldGenMinable(ModBlocks.oreZinc.getDefaultState(), 8, new AndesitePredicate());
	}
	
	private void runGenerator(WorldGenerator generator, World world, Random rand, int chunk_X, int chunk_Z, int chancesToSpawn, int minHeight, int maxHeight) {
		if (minHeight < 0 || maxHeight > 256 || minHeight > maxHeight)
			throw new IllegalArgumentException("Illegal Height Arguments for WorldGenerator");

		int heightDiff = maxHeight - minHeight + 1;
		for (int i = 0; i < chancesToSpawn; i ++) {
			int x = chunk_X * 16 + rand.nextInt(16);
		    int y = minHeight + rand.nextInt(heightDiff);
		    int z = chunk_Z * 16 + rand.nextInt(16);
		    generator.generate(world, rand, new BlockPos(x, y, z));
		}
	}

	@Override
	public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator,
			IChunkProvider chunkProvider) {	
		switch(world.provider.getDimension()) {
		case 0://Overworld
			this.runGenerator(zinc_ore, world, random, chunkX, chunkZ, 20, 0, 75);
			this.runGenerator(antimony_ore, world, random, chunkX, chunkZ, 20, 0, 75);
			this.runGenerator(molybdenum_ore, world, random, chunkX, chunkZ, 20, 0, 75);
			this.runGenerator(copper_ore, world, random, chunkX, chunkZ, 20, 0, 64);
			this.runGenerator(tin_ore, world, random, chunkX, chunkZ, 20, 0, 64);
			break;
		case 1://End
			break;
		case -1://Nether
			this.runGenerator(chromite_ore, world, random, chunkX, chunkZ, 20, 0, 126);
			break;
		}	
	}
}

 

And this is the Predicate classes (same code just different names and meta for each variant of stone):

package hazmatik.sonictech.worldgen;

import com.google.common.base.Predicate;

import net.minecraft.block.state.IBlockState;
import net.minecraft.init.Blocks;

public class GranitePredicate implements Predicate<IBlockState> {

	@Override
	public boolean apply(IBlockState input) {
		return input != null && input.getBlock() == Blocks.STONE.getStateFromMeta(1);
		
	}

}

Any help would be appreciated.

Well....a Block will never equal an IBlockState...

Also, you shouldn't use getStateFromMeta, use getDefaultState().withProperty(...)
