I’m no professional mate but I have done a lot of research , I would given the plant a root stimulant to increase the beneficial bacteria and fungi in the soil to promote root growth . I wouldn’t use any bloom nutrients yet as they are high in P and K , best for when you see the plant flowering . You should be focusing on veg growth , more nitrogen then anything else, I use bio bizz grow, bio bizz fish mix is good at this stage too . I wouldn’t use tomato fertiliser but everyone to themselves , just my thoughts from everything I’ve read . Good luck and happy growing mate 👍🏽
