I most definitely know i have some nitrogen toxicity going on, but what is the orange spot?? I was told it was a calcium deficiency, but there never were any signs of anything leading up to it before, it was just like overnight. And im in week 4-5 of flower and most of my stigmas are all orange and crispy. Can temperature fluctuations play a part in the color change?? Longest post ever for me lol, thanks for the help in advance.
