This is what I normally use by itself almost out of it going to reorder and want my tree to really take off. So thinking if I mix citrus feed and most 50/50 will be near perfect,mix for trees. Peace

Is the tree in ground or in a container?

Container trees

Don't like that trace mix at all. Citrus need a lot more magnesium than they do boron (which is easily toxic in even small amounts), copper, etc.
If they are in sulfate form, they are not readily taken up and are a lot slower to correct any deficiency if the pH is not right.

In a container I would ditch the jacks citrus and go with the jacks high performance 25-5-15. It has all the trace you need and has the 5-1-3 ratio you want for citrus in containers.

Thank for feed back trying chose the best and weighting options
