Demasiada humedad con los riegos o demasiado fertilizante , intenta que se seque lo antes posible , y a la hora de regar bajale la dosis de fertilizante y riega con agua para que en 2 dias maximo tengas que volver a regar .

Coco grower? pH should be lower lol 6

Check ph 6-6.5 range if that good you know ur not in nute lock out. By how light green she is an brown spots ima say your nute defficient on N an P. Can add cal mag or worm castings to top soil if keeping it organic. Or bottle nutes are fine just don’t forget to flush later on.
