Those look beautifully healthy
If they were mine I would simply bend and tie as suggested above, I continue training right through until well into flowering, bending gently...where you need to try adding a 'counter tie' so that you dont place too much strain on the stems/roots, ie: you pull back with one and pull down with the other if that makes sense!
It wont harm them at all if done with care and you will get a much better penetation of light to those lower bud points, if you pull tops down it diverts growth to lower tips.
Great plants, WW remains one of my old favourites!
Essentially, you twist the main trunk around a bit to get the plant matter soft and then literally just let it fold without tearing the skin. All you've done is caused internal vascular damage to the plant, which it can heal from quite rapidly if you don't tear the skin. Once the limb is downish, tie it to its base so the top cola can't come up more than horizontal. In a few days, the plant will heal and the top cola will be pointing skyward again. The difference is that you will now have 2 top colas and a much shorter profile. Good luck, dude!
