Over a week we started having problems with algae which continue to grow despite steps eliminate the problem. We've created shading, and reduce the water level in our grow beds, its slowed the spread but still has not disappeared. At this point I'm looking into adding some Humic acid to sump tanks in order to darken the water up so that the algae will die off.
Here's good video regarding algae and humic acid.
Hoping this will do the trick as some new algae has appeared in the new grow beds at are currently cycling.

Another problem we're having is nutrient deficiency, mainly iron. I believe this due to us jumping the gun planting before completely cycling the grow beds.
The yellowing indicates a lack of iron and other nutrients. To fix this we are adding
Chelated powdered iron Fe-DTPA and Seaweed extract called Maxicrop which contains nitrogen potassium, phosphorus, sulphur, iron, copper, zinc, zinc, manganese, etc.
Here's a link to some good information about the best choice for Chelated Iron.
