Iwill start in looking on your Plant, she grows very Vigor, but the internodial distance is very small. So you may need a week longer to start with her LST. Nearly every Plant responds very Well to LST, its a stressless tool to expose the potential budsites to the Light , to have a better penetration and growth.Your Girls needs to have alonger stm to Start LST, so i would chek the distance to the LIghts and give her more distance/ lower Power. So the Plant stretches more in the Search for LIght. That is going to take only a few days and you will be able to start LST on her next Week.If she continues to grow vigor, you can think in topping her too. It always depends in the single Plant if you use the " topping Tool". But LST i recommend in every case. happy growing
