This leaf spray has been developed by Blackjack Soil Company™ to enhance a plants bloom growth. It doesn’t take much to make a big difference! For a test spray three plants. On the first plant use the recommended dose shown on the label. On plant #2 use twice the recommended dose shown on the label. Use three times the recommended dose for plant #3. The plants will tell you what they like best in a big way. Great as an experiment but even better to help you understand your plants better. Start using the leaf spray in vegetation, 5-10 days before switching your plants to a 12/12 cycle. Continue for the first 5 days of 12/12. Look out! Great results!!
