is there anything else I can do to save the plant?
If you really want to save that plant I can try to help
Here's what I need to know
1-What is it growing in
A) Top Soil
B) Pre nuted Soil ( miracle grow, Ocean Forest , Ect )
C) Pro mix / No nute soil
2-Are there holes in the bottom of that cup for drainage
3-What are you using for a light source ?
A) It's not enough so better question is how much are you willing to spend on a light source ?
4-What are you feeding it
A) Are you feeding it
B) What is your water situation on a scale from I scoop water out of the latrine too I use RO water and add my own cal mag back in where do you fall
C) Do you know what a PH or PPM meter is or what it would be used for when growing a plant
5-Are you in a place where this is legal and have access to a hydro store or do you need to keep quiet and use what you have available
6-Do you know if that plant is a female ( grown from feminized seed ) because if not this is going to be a lot of work for a 50 / 50 shot at it having balls
7-This is not a question Go buy an oscillating fan and potentially a bunch of other stuff
8-If you made it this far, are you really sure you want to save this one or do you want to get set up correctly, start over, and invest your time into something well done from start to finish. At most you lost 3 weeks on that plant.
( I will take on the challenge of trying to help save it just so you know
