nutrient advice

hey there i just went to 12/12 on my girls. i havent used any nutes only spring water for two weeks and want to start using nutes for the flowering process. i know alot of you like the FF stuff, but there is a few diff kinds. what do you suggest? my grow is in soil, under 400w light. also what dosage should i be using from the start? and what should i know?

oh and i was using the jacks professional 20-20-20 for the veg cycle if that matters

no help anyone? as much as you guys love talking about nurtients i figured youd be all over this one, please help

just stick with jack's blossom booster and ull be good.

tiger bloom is for flowering, get that and if you want some big bloom, which you use in both veg and flowering to help the roots system among other things. I use it.
