Ok, please forgive if this comes off sounding harsh. You obviously have a passion to grow your own meds, that is very good! Passion and dedication will bring good harvests in time. It does not look to me like you have invested a lot of time, planning, or cash for this set up. So, you should not have that much to loose.
I suggest continue to grow them for the experience which will be invaluable. While they are growing take that time to read, study, plan, and then act on a new grow. You will have time to save some $ for better equipment and learn a ton of info and have a much better grow.
The link in my signature is a virtual classroom of how to videos from grow masters for 1st timers. And RIU is a very valuable resource for great suggestions and great people to help. Best of luck!
