Usually, when the fish get a bit sluggish, the water pH is getting too low. I did not have time to check the pH today, but saw the fish showing slight signs of sluggishness. Added two teaspoons of lime to raise the pH. Added one teaspoon of iron for the plants.

pH was very low again. Below 6.0. Added four teaspoons of lime to bring up the pH. Also added two teaspoons of kelp extract and one teaspoon of chelated iron.
A couple of weeks ago, I dosed this grapefruit tree with chelated iron. The leaves look a bit darker now.
The lettuces are growing very slowly. They have already been dosed kelp extract and now experimenting with chelated iron.
These are the before pictures to observe results.
The watercress are spreading out nicely though.
This mustard lettuce has been growing well too.

This grapefruit tree has leaves that look like the tree is lacking iron. Dosed with a teaspoon of chelated iron FeDTPA sprinkled on the surface. Then watered to soak into the soil. Date of treatment is 10/23/2014.
