No secrets.
I'm using AN 3-part with Big Bud for my flower booster, Rhino that I start using very early in veg at low doses. A little bit of Growtek CalMag and some epsom salts from the drug store.
I don't change my nutes until after the stretch if then but go to a Lucas Formula type feed with Big Bud when I do to limit N in later flowering. I start clones around 300ppm using a 1-1-1 ratio, GMB, of the 3-part then once they are growing well up the ppm using a 3-2-1 ratio. A week before flipping to flower I up the ppm with a 1-1-2 and a half dose of Big Bud then give the other half dose when I switch to 12/12.
I had bought a 250ml bottle of Bud Ignitor a year ago but it didn't seem to do anything in soil/soilless but still have 1/3 left so will experiment more in DWC. While in BC last Aug I got a free 500ml bottle of Bud Factor X from a hydro store I shop at when there. A couple online buddies swear it's the bomb for getting bigger buds and more resin when used with BB in DWC so will be experimenting with it now too. Tried the OverDrive a couple times and saw nothing so won't use that again.
That's the basics. Going out to check out a car we might buy so got to run.
