Clone Transplant Need Help!

Hello I am new to this forum and also new to growing. I am starting out with one plant and I designed my grow room by myself. To save time I wont go into detail, it is a big rubbermaid storage container sitting vertically with a Mars 300 LED grow light and two ventilation fans(intake and exhaust). I recently purchased a Clone from a local medical Marijauana garden dispensary. The clone is Girl Scout Cookies and yes I am from San francisco so it is real cookies. When i got the clone it was nice and perky with small roots poking out of the rockwool. I mixed fox farm ocean floor soil with a tiny bit of happy frog and I added a little bit of Dolomite lime with Lava rock at the bottom. I wet the soil so it was nice and moist, put my clone in covered it up nicely and watered again. The first day it perked up and seemed to love it but the next day It started to wilt and kinda fall down. Im not sure if I should take my clone out of the soil and transplant it to a smaller pot? I also watered around it to make sure it was not just thirsty but that did not seem to help. If you have any ideas on what I should do I am all ears. I would hate to lose this little guy as it is my first plant ever. Thanks in advance!

Most likely its overwatered...putting a small clone into a huge container then watering the shit out of it is not good. Yes, Id put it into a smaller pot and not water it till it dries out 85% , Water it just enough to dry out in 2-3 days after it dries out ...this helps incorporate a feeding schedule in later on. If this plant shows yellowing in the near future, top it off with some fresh soil and give it a watering...same thing..just enough to dry out in a cpl days.

Hi thanks for the reply, I went with my intuition and decided to re plant it into a tall red solo cup with just foxfarm ocean floor. I put it back under the light and It perked back up Im not really sure what it was but I think it was actually under watered
