my ph water has sulphites in it will my clones not root?

i soaked rockwool in water ph'd with lemon juice but after reading the label it says it contains sulphites will this kill my clones?

In my experience, with rockwool it's seems hard to get it stable, your using lemon juice instead of some PH down, I found that the lemon juice is unstable an it will most likely raise the ph after a an hour or 2, are you using tap water?

yes tapwater, my main question is will sulphites harm the chances of root success? im thinking sulphites will kill my clones because its like a antibacterial?

it said on the lemon juice "contains sulphites" shud i rinse rockwool
