GrowCNanswered grow question 4 years ago I'm not trying to be a bung hole but I have never had to stake a plant, especially at such a young age.
If it can't support itself it really needs more light. Not enough light will cause it to stretch (though your's doesn't look too bad) and focus on growing long to reach the light but not enough into structural strength. If it can't support itself it really needs more light. I even have a fan blowing on the plant to buffet it and encourage stronger stems.
The leaves look good so your nutrition seems OK at this point. What soil are you using?
