This comment just blew my mind...
Really I asked the question because frankly i didn't know what "buds set" meant.
**Cat Drench: This is used right when buds set.
I don't think this is clear at all from my point of view.
And you're right - it isn't clear at all - it's a personal judgement. There's a stage in bloom when the buds have basically established their size. From there, they swell and grow some more, but there's a point where they're "set". If we give them a strong dose of fruiting nutrients, they'll put it all into those set buds at the expense of new growth - they'll swell. We trigger them to strongly fruit for a week or two, and then give them a good shot of fish guts to bring them back into growth mode.
It's, like, three weeks or so after it shows pistils, give or take ... subjectively.
