i was recently trying to grow a sativa strain when the plant got to about 5" the stem went completely limp and then died and i am wanderingwhat i can do to prevent this from happening
Sounds like an issue from another aspect such as over watering caused the roots to root and thus the stem weakened. A fan on the plant helps it to build a stronger stem though and you can use rods to help keep the plant up or bring dirt up to the first set of leaves.
