Idk. If you cut them, you might need a cloning solution to rebuild the roots and even that might not work. I'd say put the lights closer and let them rebuild their strength that way with the help of supports. Although 20 cm is quite the length for a sprout. Here, I'm purposefully trying to grow these long and thin so I can do a scrog in my LED tent.
Yup! Great idea. I wish I would have thought of it lol.
You know how you might "super crop" a stalk? You can do that gingerly with your thin sprouts and they'd probably grow to be quite a bit stronger as an outcome so long as the light is where it needs to be.
The number of fingers on each leaf. First will have 1, then 3, then 5, then 7, usually. Might be small variation on certain plants. But i use that because i can gauge how much foliage will be left. If you cut to the first 7 point, there should be at least 3 nodes with 2 fan leaves each on that plant of varying health. Telling a new grower to cut his seedling in half and only leaving 2 leaves would be a disservice and depending on the grower, could mean dead plants. You should let it grow a bit before you do anything in my opinion as 3 weeks, if miswatered or fed even slightly, will not be a hardy plant necessarily. My advice to you is let it veg for another week and upload some pictures then for advice bending or cropping it.
me too all the way up and leave about 1/4 in from first set of leaves,,builds big stalks
