yea when they get bigger start to tie them down apart from each other. this will still work really well. or transplant two out of those last three b/c they will compete for space, nutes, etc.
hey there,
nice looking plant- it looks a little like you might have a nutrient deficiency, but its hard to tell from those last pics.
you do have a while left to flower - maybe even another three weeks or so depending on the strain.
