Crop Flushing:

“Nutrient flushing” A.K.A. “Salt Leaching” are names for removing the excessive nutrient salt build up. The reason we want to remove excessive salt build up is because too much salt can build up in the plants medium that the roots reside in. This salt build up can ultimately affect nutrient uptake of the plant. Which means the plant roots can’t feed correctly and efficiently. So therefor we must remove the salt build up in the plants medium. TNT Nutrients “MASTER FLUSH” is specifically designed to remove the salt build up so your plants can feed again at full capacity. The way to correct this problem is to simply drain the whole nutrient reservoir, to remove as much nutrient solution as possible. (Draining nutrient reservoir was previously explained in the “Nutrient Change Out” section. See the section for example if needed) Fill the nutrient reservoir back up with clean reverse osmosis water and add “MASTER FLUSH” at 30-45ml per gallon of water. Run the hydroponic system for 2-6 hours. Then drain the system by getting out as much of the “MASTER FLUSH” recirculated solution as possible. Next, fill reservoir back up with clean reverse osmosis water and add desired nutrient dosage. You should notice a difference in 1-3 days in order for your plants to respond to the flush. You should start to see your plants looking healthier and see them feeding again now.

Next, we will talk about a “Pre Harvest Flush.” The “Pre Harvest Flush” is to help our plants, while forcing them to finish their flowering stage and ripen. This flush also helps the buds to swell, by adding weight mass, by ripening the flower sets, and to use all of the remaining nutrients that are stored internally in the plant. By doing this, the final outcome is a smoother, more aromatic, flower with oil rich buds. This task is the same as stated above on flushing. The only difference is we want to use 45ml. of “MASTER FLUSH” per gallon of clean reverse osmosis water. Run hydroponic system for 2-6 hours, then completely drain the nutrient reservoir. Next, fill back up the nutrient reservoir with clean reverse osmosis water and pH to 5.6. Maintain the pH of 5.6 for 7-10 days until harvest.
