How early is too early

Used tiger bloom for the first time last year. It did well I thought. My ? Is when should I start to use it again this year. My girl is in veg still and outside but has preflowers. Should I start using it or wait until she's in Bud? Thanks in advance

P is required all the way through but in veg they only need to sip on very small amounts.

I wouldn't go beyond 1-1-1 in veg even with pre-flowers, still i prefer 3-1-2 to be on the safe side.

If your plant is already well fed I'd hold off on tiger bloom unless your lower leaves show problems with P or if your current nutes/soil doesn't have any.

I would honestly wait until it starts budding. Also follow what the manufacturer recommends. Lastly, less is more.
