Oh okay this is easy then!
First, you need a nice GROW fert that has nitrogen in it.
Next, the soil pH needs to be 6.5-6.8 and you are WAY high. So... Flsuh with water at about pH 6.0 to lower it until it is in range. The final step of the flush once you determine that your pH is correct should be with 1/4 strength grow fert. If you are going FoxFarms, that would be the 'grow big'.
I like the easy problems to fix!
