Jef79answered grow question 5 years ago Hello.. Hope you are well.. Personally i think itsjust wer the leaf has been sitting on wet soil n edges have burnt.. Her other leaves look fine tbh.. If ur worried bout an over feeding issue then on nxt watering just give her plain ph'd water n this will help dilute any left over nutes in pot, carry on with normal feed program after but maybe drop nute levels a very small amount if ur worried.. Stay safe n gud luck with her.. 👍🍀
