I attempted to foliar feed my youngest plant yesterday with foxfarm grow big diluted in water of course. After i sprayed the leaves, I did notice there was droplets on some leaves and the next day every spot there was a water droplet now has brownish spots. I read somewhere about using some sort of detergent to eliminate the droplets, but not sure what to use. Also, im assuming the spots will be there for the remainder of the plants life. Is this an accurate assumption or will it eventually disapear.
