Recycling happy frog soil w. hf soil conditioner....

OK ive been recycling my happy frog soil with the happy frog soil conditioner and im not sure to the amount of used soil to conditioner, anyone with experience doing this?

ive been adding 1 gallon of conditioner to one of those big blue toats with the wheels on the one side, full of used soil but it just dont seem quite right i get some brown spotting and some purple on the stems and the stems dont get as big as they were, if this info helps any suggestions would be great

Just flush with water a few times and start like it's new. Watch the plants for nute deficiencies. It is said soil does not achieve the max beneficial microbe populations until it has been used 2 to 3 times.

oh yea ive been running the same soil (recycling it that is) for like the last year or a little over...

I would add some dolomite lime. It helps sweeten the soil or medium and get it ready with calcium and magnesium for the next bloomers you raise.
