Not sure what’s going on here. Any insight would be hugely appreciated! Added an overhead pic of the whole plant. None of her sisters are having this issue.

It is either a ph issue in substrate. Check run off ph. If that is in a good range. Additional magnesium and potassium would solve issue.

Yellow/brown splodgesHi there
My plant is still young @ just over 2 weeks now. She has these brown/yellow splodges on only one leaflet but the new growth is looking a healthy green, so im not too concerned at this point. I am curious as to what it is though. What would you guys suggest it to be?Leaves. Color - Yellow

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!2y ago

orange sherbet crispy leaves. Close to harvestFastbuds Orange sherbet first grow. I already harvested this plant but I’m curious what the issue was. The leaves were yellow and crispy to the touch. Other leaves looked fine. 2.5oz harvest but it dried really fast(7 days) and now smokes harsh. Don’t want to repeat this mistake.Leaves. Color - Yellow

-Watering : 50ml every 2 or 3 days
