The only places that perlite holds anything are the open pores on its surface, it does not hold nutrients well.it will always hold it perlite holds nutrients an releases it soon as water hits it perlite is a sponge and there fore once you feed your plants the sponge type perlite will absorb the nutes then it drys up but once water touches perlite it will release the nutrients it had and so on
