Good Luck on your new grow -
As for advice on LST - the best I can give is make sure you have enough root/time to handle the stresses and recover. (a little silica in your nute feed helps too)
In veg it's easier to tell how much growth you have underneath by the number of nodes that grow since your last stress. (so like when I top the first time I like 5 to 6 nodes of growth and then I top down to the 3rd and remove everything else - but to top for the second time I want to see 3 more nodes of new growth from that point even if I plan to top down to the first node again... ect., ect.)
