Yellowing Drooping Plants

It seems like a clear case of nutrient excess. The excess salts have blocked the roots, and they can no longer absorb nutrients from the soil. The only solution is to perform a root flush (2L of water for every L the pot holds); if your pot is 11L, prepare 22L. I recommend taking it to the shower and draining all the water there. Prepare water at pH 6. + 'Flush' solution (Final Flush from Grotek or Canna Flush) https://thgrow.com/es/grotek/3528-final-flush.html this way you can wash the roots and clean the salts that are obstructing absorption in the roots. Remember: Adding more fertilizer doesn't mean better quality. Good luck, my friend!
