My soil is called Filthy Rich by Dr. Q. Already has plenty of castings and shit.

I've got the Cha Ching, and will continue to properly use it till it's gone, but won't re-order it again. Be real careful with any of the FF solubles...it's some very potent shit. Be careful when using it in conjunction with your normal nutes.
The plants show flowers eventually, so it's not worth the extra expense in my budget to get the Open Sesame, and I've never used the Beastie Bloomz.

I do use Soil Syrup (humic acid) twice monthly per directions, and Botanicare Sweet on occation. (but I'm not sold on the 'Sweet' stuff)
The Soil Syrup is one I'll always have on hand. With Fox Farms, you'll get minor salt build-up. I correct this condition with scheduled monthly flushes, (veg and flower) folowed immediatelly by a full-strength solution of the humic acid.
Even though Fox Farms Grow Big and Tiger bloom have your micro's, I still use Superthrive in veg. One or two drops per gallon, depending on plant maturity.

Be careful with mixing shit together. It doesn't always work out for the best.
