I also wait to lst until a week or two before I start bloom. This is also the same time I figure that the plants have vegged just about long enough for my height requirements. The LST slows the vertical stretch and promotes many budsites. Also, I wait to tie them down until the pots are dry, ready for water. Tis is when the plants are most flexible. Don't try and do a lot of major bending when the plants at 'wet'. They snap easier (just like a fresh vegetable or a dried out vegetable).

Neptune fish and kelp emulsions are great stuff!
