Drench: Mix 140ml SNS 203 per 4.5L of water to make a ready-to-use solution. Thoroughly drench affected and surrounding areas.

Spray: Mix 2 to 6 oz (56ml to 170ml) or (4-12 Tbsp) per gallon of water (4.5L). Spray foliage to the point of runoff. Repeat 2-3 times, as needed. Do NOT spray on buds or flowers.

Hydroponics: If you can, remove plant from the system and place in a 5-gallon bucket. Pour solution over top of the root system and drain into the bucket. Let sit for 5-10 minutes, rinse with water and return plant to the system. Apply 2-5 times every 2-3 days as needed, depending upon pest infestation.
