nice looking buds my friend,
i find pipe cleaners are the best for lst as you can bend them where you like and they dont cut into the plant, in your pics you use something similar by the looks of it, wire works and wool works, but one thing everyone needs to remember is the main stem is still growing, so once a week or every 10 days it best to adjust your ties so the plant can stretch a little, not doing this can cut into the stems,
another way of getting bigger buds is to remove any growth at nodes that is not getting light or any growth that is small, these small pop corn buds are using the plants energy to grow and taking up nutes, removing these means the plant focusses its bud growth on the buds getting the light, this means these buds are getting all the plants energy and its not wasting time on pop corn buds and buds that are not getting much light, basically when i lst my plants and it ends up like a scrog i remove anything below the canopy, a 400watt hps has a light range of about 1ft, anything below that range is getting less than half the light it should be, so these buds will be slow growing and wasting the plants energy, i either use these as clones or if i got enough clones just bin them, or if you have mates that grow and its a decent growing plant then turn them into clones and offer them to mates, then in the future they may return the favor with a top strain their growing
not all clones need to have big stems, i have turned 1inch branches into clones, some of my clones just have 2 or 3 leaves above soil level, these tend to root as quick as clones with longer stems, so if you can turn them into clones and benefit from them or a mate can benefit from them then id turn them into clones and
donate them to someone that can use them,
also taking clones from a flowering plants means you need to reveg them, this takes about 3 weeks to go back into veg, but what you end up with is a monster cropped plant, basically this is a plant on steroids, the branch growth is crazy, ive had branches growing out of the stems of the fan leaves, the monster cropped or revegged plants seem to behave a bit crazy and you end up with many many branches, grows more like a bush than a cannabis plant,
my plants look like a scrog due to lst, basically which ever stem is the highers becomes the main cola, so pulling down the main stem forces the plant to grow quicker at other nodes so it becomes the top of the plant, what i do is pull all my side branhes down so their running outwards, doing this makes all the shoots at the nodes grow upwards and these then become decent sized buds,
