If you don’t have a growlog please answer these questions.
What strain are you growing? Is it Auto, Fem or Reg?
Are you growing Indoor or outdoor?
Are you using nutrients? Which ones? How much?
@Crackadoo and @Nelson gave good advice, transplant into a larger pot, consider topping it to encourage lateral growth. the last thing for a larger plant is More Light.
It must be dry, in that way, the structure made by roots can hold the soil in between them. That is why it is so important to wait for the right moment to do it. We need the roots to fully colonize the pot before transplanting.
I mean u can put it there i seen people put it in those plastic red cups with dirt on them with draining holes on the bottom but yea u can do that also it’ll take a week or so to see the new roots so give it some time
