Yeah, if you are going for the contest of weedseedsexpress and you have other seedlings growing then i would risk it and top it on top of the supercropping, after all if it works it works and you will most likely win the 200โฌ, but if it fails you can just go into the contest with another diary/plant.
Good luck, hope you get one of the prizes, since there are 10 and not that many participants, if it goes well you basically have a prize guaranteed.
Stay lit growmie.
