That's not a deficiency brother that's nutr burn . See how the ends are curling up and it's just got that burnt appearance. You need to water to run off or water between feeds and check your ppm in run off .
@Grower202085, yea im growing organically.... i have being experimenting with different super soil mixes in my last 2 grows and only realised half way through my last grow what the problem has been. My soil ratios is way off and my super soil still too hot.
All that said, she still produced 3oz of super bud.
We live and learn i suppose ✌️
