Hey guys see week 13 day 90 last picture is it Mag...
MomnPoppaSeedanswered grow question 5 years ago
That's exactly what mine did with a cal-mag deficiency.
I thought it was light burn although it wasn't close enough to be.
But when I asked i was told to try a cal-mag supplement and it worked like a charm.
I'm new too but I just wanted to say that mine did start out with 1 like that and got more within day.
Good luck, she's pretty otherwise and the one I had do it is now my most beautiful plant to date.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!a year ago

I did lower the plant (was way too high) so may beight burn - but it’s only on some plants
I did make two mixes of water/nutesWeek 8

Tache cuivrés sur feuille.Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda.
