Since I don't see it on any of the other leaves just the very top ones, I have to agree with you on the light burn.

Heat or deficiency? Or something else?I'm noticing some sort of deficiency or toxicity. I need help on figuring it out. I water with distilled water, cal mag, and 1/2 strength bloom boosters. Ph @ 6.5.
Could it be heat? It gets a little over 80 F. I have AC running, It's still cooler than outside in the sun thoughWeek 6

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

Problem with front middle purple punch. Info provided(See description for more); Temp: 71-79.5F, RH: 46.1, DLI: 40-50(decreased today due to tacoing)This is an organic grow using Coast of Maine Organic plant food, and lobster meal. It appears to me that the plant has deficiencies for all the three major nutrients, or lockout, but today it is also showing what appears to be Calcium or Magnesium. I've been using castings too.3y ago

Saw a lot of yellowing in the flowers, not sure if its enough or too much nutrients, or not enough water or its a pest. I was suggested neem oil to get rid of the pest creating those white spots, any other suggestions about how to get her to look healthier and growing faster?Week 6

I’m at week 6 day 6 of flower on my ssh. I noticed some leaves turning yellow. I think it’s too early for them to show their fall colors as this is a 9-12 strain. My ph is always 6.4-6.8. My runoff ph is 6.6 always.I did move my lights down and just raised them. I’ll post photosWeek 10
