Looks like potassium to me. Do not raise your nitrogen level in process. Your well fed there. Always be aware of run off ph and tds or ec.

Exeso de luz? Bloqueo de nutrientes?
Los nuevos brotes de mi planta salen con un tono verde lima. En la zona que más luz hay parece empeorar, será un exeso de nutrientes/bloqueo o quema de luz? La lámpara está a unos 40 cm
