i use a spray bottle with soap and water mixture, very diluted, fort tomatoes though, dont know about using with MJ wait for other replies
chili or pepper powder mixed with water in a spray bottle spray around and on the plant and like the poster above me said take a few shavings from a bar of soap and and mix it with hot water and put in a spray bottle and put a thin layer on the leaves this will keep those fuckers away but the pepper spray really has been working for animals for me as long as i spray a good amount around the plant after it rains
no, you want to avoid putting any salts into your plants soil. it will cause nutrient lockup. anyways, i made a chili and garlic spray that i used on my plants. it killed every bug in sight. heres the recipe: 2 cloves of garlic 2 hot peppers (i used cayenne) half blender of water blend this mixture and store it, calling it the "concentrate" when using the mix, use 1/4 gallon concentrate per 3/4 gallon of water you really can use any combination of concentrate to water, but if you dont want to keep remaking it you can dilute it.
