white dots ( spec's ) on the leaves

[spec]

Hi from Australia. Have just set up yet another Hydro room. Every thing seems to be going well after a couple of weeks other than a couple of the plants have white dots ( spec's ) on the leaves. Started out on just the one and seems to have moved on to 2 other plants. Other then this everything looks healthy Should I worry ??

Maybe. I would watch to see if they have any negative affects on you plants.
