What happen?

Ceramic pots give me the eebie jeebies, 80+% of problems arise from improper environmental. Which in turn leads to symptoms that appear nutrient based. You really need to have a solid background knowledge of what is happening within the soil, use of ceramic pots leaves very little margin for error when it comes to cardinal variables. No diary, can't be more specific without specifics. I'd advise you look up the 9 cardinal rules for growth, get yourself some airpots which are far more forgiving for beginners. Anything above 77f ambient and bacterial growth explodes. X10. If there is any moisture trapped anywhere, dead spaces with no air flow its just a matter of time. Oxygen to rootzone can be a limiting factor preveting nutrient uptake, waterlogged

Heavy imbalance in feeding and ( i would guess from look ) watering regime issues too. You have nitrogen toxicity and lockout most probably, plus heavy lack of phosphorus. Diary would help to diagnose and advice, now only random shots without reasoning ...

Okay here is the issue here, You are feeding your plants to little nutrients, your girl need more base nutrients. NPK. Also add more Calcium and magnesium! So just give it more A/B solution or Veg solution in your feeding mix. And buy a solution called Calmag it contains both calcium and magnesium. I’m not sure how good she will recover even if you feed her the right stuff, but now you know for your future grows. Add more NPK and add calmag Good luck my dear friend.

Seemt to me like a advandce lack of phosphorus
