Questions regarding fertilizing in flowering stage

I was told by the guys at the hydro store told me with the soil i purchased that i wouldnt have to fertilize in veg growth but he sold me some bloom builder for flowering. my question is should i apply it on a regular basis or every week or 2 ???? Thanks

What brand of soil are you using? Some organic soils have enough nutrients to feed your plants throughout veg. Read the instructions on your bloom nutes, start at 1/4 strength and work your way up.

im using fox farms ocean potting soil

3-4 weeks in veg with FF-OF
after that you should think about feeding.
Use the Bloom like the directions say or the Feeding schedule.
watch your leaves, if you plant looks good, your good.
IMO- your probably going to need a couple more nutrients, and a bottle of Cal/Mag

Good Luck on your Grow.
