I go with their schedule, with two exceptions.

I go half-strength on the Big Bloom. Indica dom's handle it fine, sat dom's tend to show a little burn. The FF people told me that the Big Bloom and the Tiger Bloom have your micro's, so no need to add more...and that the Big Bloom is the catalyst. (it's a tea of bat guano and worm castings)
Keeping these ingredients in mind, I use an organic peat-based soil with castings and fungi already in it, and have never used Happy Frog. You'll want to adjust the Big Bloom accordingly.

Also, I feed twice a week, instead of once. I cut the rates in half to be less of a 'mega' shock, but they still get the same weekly ammounts overall. Plain, ph'd water inbetween if/when necessary.

The only other additive I use is Soil Syrup. (humic acid) With Fox Farms, you'll get some salt build-up, so monthly flushes are a sucessful part of my regimin. After the last bit of flush, I'll mix-up the humic acid, and add it to the soil then.

If using R/O water, you'll need a source of calcium. (CalMag is fine) Is there something wrong with your tapwater?
