Hello everyone, I am nearing the end of flowering (maybe 10 to 14 days away from harvest) I am growing GSD extreme feminized and the very tips of the leaves are browning. Is that normal or do I have a nutrient issue.
Pics or it didn’t happen.

Agree with above. Could be nothing to worry about, or could be onset of this or that. The world may never know.

I ran into a nute burn problem about four weeks into flowering. The very tippy tips of the fan leaves turned brown and started curling. I am growing in coco coir with canna coco A and B. I water four times a day during lights on. I measured my run-off and the EC was way higher than what I was putting in, so I had to flush with pH’d water a couple of times to get the run-off EC close to the feed EC. I also dropped my feed EC to 1.5. I think I caught it in time. Sorry, I don’t have good pics.
