I agree with hotrod, more light and closer. These girls are stretching way to much.You need a lot more light and get them closer to it.
Edit posting:View attachment 2614439here they are I'm trying to prop them up on something so there not leaning
There should be a fan in the room moving the air- but never pointed directly at the plants---
aimed above them is good- but not straight-on...
turn them the other way around- and use a length of soda straw slit up one side to hold them up-- just cut the straw to be slightly shorter than the stem- open it at the slit and CAREFULLY fit the stem inside and push the straw into the soil just enough to hold it up...
I'm sorry- but those are SO STRETCHED.......
what kind of light you using and how far away?
The stems should be about 1/3 that length at that age....
you can get them stronger and make it work, but it'll take time....
You MAY have to coat the stem with cloning gel and plant them real deep to re-root if they can't get strong enough to stand by themselves....
