Whats wrong with my Chimera?

Looks like you stripped a bunch of leaves at a point where they could not grow back - bunch of small immature leaves are all that exist top to bottom. That's not helping your plant. Never approach it with incredulity - e.g. 'the same fertilzier, the same light' because obviously, even if true, which likely is not as hard as any 1 person can try, there is clearly something going wrong. At that point it is completely irrelevant if you think it was treated the same. Not all plants are equally robust to all imbalances. Some may react more poorly than others. Some may have different needs but this is far more rare than people perceive, because it's easier to blame outside sources than anything we do.. too often fertilization is for some odd reason intertwined with ego. A good formula can work with 95% of plants, but the proof is in the pudding. If it does not do so, it's not a good formula. deductive logic, not inductive... top-down perceptions only lead to mistakes. As far as the leaf symptoms, seeing the progression would help. Stripping all those leaves is part of this problem, or at least exacerbated it. You would have had more room for error because those leaves are storage facilities. It would have gone downhill more slowly and easier to react and reverse it, too. Wow, this all happened in 5 days? Definitely overfed in general, but depending on balanced doesn't mean any 1 element can't be low, but less likely so. See a lot of bloom boosters being used. Probably gave it too much K and maybe others. Again, having those leaves would have made this less of an issue with much slower progression. Beware of bro-science... a lot of the most commonly repeated things are nonsense, lol.
