Blotched spots on fan leaves - calcium or fungus?

HazeyBobbystarted grow question 6y ago

Started noticing some funny spots showing up on the big fan leaves. Light colours patches in non-uniform shapes-looks like it's spreading across a few of the big fan leaves only. Not sure if it's calcium deficiency or a fungal infection. No insects noted.

I don't believe it's an insect/pest issue - I've been checking everyday with a magnifier for any signs with nothing to report. Seems to be a deficiency at this moment.

Do not worry, nothing will happen to a stain, but it may be a warning that there is some mite over there that is leaving its marks, if you can not be the same leave that is so 🤔🤔 https://www.google.com/amp/s/www.dinafem.org/es/blog/como-recuperar-plantas-marihuana-plaga/%3famp

Should I defoliate light-blocking leaves from my NL auto?My NL auto is at D40 and is growing well. She's developing a good lot of cola's with nice bud sites. Up untill now I've been able to tuck the leaves away, but it's getting more difficult to keep all bud sites cleared as she keeps growing. Should I tactically defoliate?
