I too think that Solar & Thorn already being level 2 forms are more likely than being of level 1 like how Tanah, Petir, etc were. I mean, unlike how BBB got Api & Air, which is by unlocking them through experience, Boboiboy got Solar & Thorn (Blaze & Ice too) from Ochobot's 'hack'-like upgrade. Also, I think Solar & Thorn's first forms might've been something along the lines of light & nature respectively.
