For Lavender you do not want to add any fertiliser, just add in lots of grit or perlite.
So I would weed, dig over the soil adding in grit and perlite then the Lavender. And that is it. You feed Lavender then they get leggy quickly. I would then top dress with a stone mulch to keep the soil warm and it is easy to pick out any weeds.
