Stretching finished and I decided to defoliate this is day 22 of flower. On day 20, I added nute Recharge to my normal nutrition amount from last week. I usually add this a couple days before I defoliate. Run your reservoir low then make 1 gallon worth of feed per plant your running into. I'm running 3 different plants so I made 3 gallons worth. That amounted to 1.5 of recharge. I usually allow reservoir to empty, and I clean it out and add normal nutes back without the recharge. Recharge messes with my ph machine and doesn't give accurate readings.
