i use the motto, "if you can't tuck em, pluck em." i always do a lot of trimming. you can still trim with no problem. i spread out trimming. cutting too much at any one time can cause a lot of stress. you're kinda late into flower, it looks like. i begin tying down in flower, but you may be too far along. the later in flower you wait to tie down, the slower the response. if i tie down at lights on, before lights off, they're already facing straight up by the end of 12 hrs. but this is within the first week or so of flower. i seldom tie down after say, 2 weeks in.
