Dose anyone know what this is and how can i fix it ?
Need a pic
Kinda hard to tell with the lighting but it does look like it on these leaves.
This is what mine looked like and I just foliar sprayed with calmag due to the chelated iron in it. Took care of it within days. The source of my deficiency was a water conditioner I used to remove chlorine. It also removed the iron from the water.
So i should be able to use the cal mag that’s for the ground on the leaves … ? How often en were u spraying them ?
I wouldn’t seeing you’re in flower. I only foliar spray in veg. I’d be sure to add calmag, or a nutrient you have with chelated iron on your next water
