Chimera whas a Monster in the "old"Greek-Times

That look like something you've done through the whole grow as its clearly stunted.

I check diary too, something happened during last week. I dont speak about strip damage you done till this point, you obviously havent tried to grow a plant without any training, what i would recomend, harvests would be way higher than with current approach. When i did mistakes and put too acidic feed - i had similar burn as yours, it was happening in hours after such mistakes. Triple check ph meter, they tend to brake or just go bad Think last feeding was with ph 5.0 or lower, thats the aftermath ... Doubt you can change much. Soil can't be flushed from such damage without creating even more problems. Plain water till harvest and reduced light intensity - that would be my actions in such case.

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.
