First you did no harm by doing this LST and topping I would suggest having the pot full of dirt so the plant is higher up in the pot to make bending and tying down easier next time.
Also see water droplets on the leaves it can act as a magnifier under the light burning them so try to avoid
I would also suggest starting following @kaptain3d threads he does a lot of training check it out here Kaptain3d's Sunken Treasures 🏴☠
