That was a cheep way to try explain streaching.
Now I had breakfast & a smoke or four


In veg if a plant that is *stretching its stretching for the light.
Once it enters flowering stage during the transition from veg to flowering ( the first two the three weeks ) it naturally stretches.
You can minimise the stretch buy having the light the right distance away albeit you need a stronger light when flowering than you can get away with in veg.
* stretching is the space between one set of nodes & the next set as you can see there’s a distance between your nodes witch means at some point the light was either to far way or not strong enough.
if one plant is smaller than the other raise one by putting it on a upside down plastic pot remembering to include the saucer or something else that works.
That way you have the light the right distance away for all the plants.
You can look into lst ( low stress treatment ) to strengthen up your branches.
If some of the side branches fall over late in flower you can by yo-yos that you hook up.
I’ll post a pic of them as if I link you to them on Amazon it will probably ask to change country but you can by them your side.
