Algae on my Rockwool Cubes?

I have done this because they don't seem to burn and because they can consume the whole entirely of the reservoir in one day at their peak flowering cycle. In Veg my plants can drink as high as 1400 PPM which seems crazy. But as soon as I flip the light cycle this drops to about 600-700. .5 conversion And I...
