Spots on leaves

HappySkunkstarted grow question 6y ago

Could this be the beginning of a Phosphorus deficiency? Or something else? It’s not really found on my oldest branches, but more my newer ones.

I would say that's a slight calcium defeciency, just add some cal mag to the feed.

Glossy lower sword leaves surrounding colas I noticed on some of the lower buds, the small sword like leaves clustering around the buds have gone a bit glossy. Isn't this usually nitrogen related but there's no evidence or much tip burn. Should I lay off the nutes for a Few days?

Spots/decolouration on leaves: 1 sideplant (that I grow next to my growlamp) is getting a few spots....So, I have 3 plants: - 1 centerplant that gets most of the light & 2 sideplants (left and right) who also catch a lot of the light, but not as much as the centerplant: the sides arent getting direct light, more reflective light. ?? The left plant is showing a few defects. Anyone?

Problemas de ferilización?Que opinan sobre está carencia/exceso en estás plantas? Ambas tienen 4 semanas y han mostrado esos indicios solo en las hojas viejas, pienso que puede ser déficit de calcio/magnesio, aunque no controlo pH, así que es un factor que también quizás debería considerar. Que opinan?
