cloudy water is probably a sign of a bacterial bloom since you are in the middle of your cycle. if it doesnt clear up by the end of the cycle (0ppm ammonia and
nitrite, 5-20
nitrate) then you might have some other problem, but for now i wouldnt be too concerned about it.
you've probably already heard this, but you should be doing 50% water changes and raising your temperature to 84, to get your fish through the cycle without causing harm to their internal organs and to treat the ich, respectively.
