Shining silver lemon haze

Day 29 from sprout , - Topped plant 2 yesterday as did plant 1 last week , plant 3 think am going to just leave and see how things go with that one , starting to see a lot of growth on plant 1 after topping not sure if I fimmed it or not now as we have growth we’re I cut it all off ... pics attached. Other then that all look and doing very well slight Nute burn on tips of some but that was from while back flushed and hopefully probably fixed - not to sure when to start LST on plant 1 may wait another week untill stems slightly longer with it being so bushy
