Trellis in flower

Just started week 3 of flower and my plants have stress too much they are almost touching the light already can I trellis them still or what do I do

Sure can, as long as the branches still flex it will be a pretty easy job. Keep all the sides of the trelis secure to the walls or a frame or whatever cuz when the plants grow they will try to take that thing up with em. You can even use adjustable zip ties or twistie ties to keep the branches where you want em . Used to to this years ago on smaller grows and after the branches were bent flowering sites that would have normally grown a small bowl were growing small grams!

Thanks for info I'll get to it ASAP

I waited too long to apply a trellis and ended up snapping a big ass branch as I was trying to get it on. Not good as I was in week 4 of flower. I ended up taping the branch back together and I think the cost is clear.

I decided to leave it off this grow and be sure to get it on at the right time in veg next time. I have a few colas that are really close to the light, and my plan is to use string to move them over and down in the next couple of weeks.

It seems like the science is still not out on what happens to the tops that get bleached by (LED) light in flower. Anyone care to share there experience?
