Durban Poison SCROG SIP (Sub Irrigated Planter)

Welcome to week #4 since the flip to 12/12. This might be the shortest scrog I’ve seen…haha. i flipped them pretty young since I’m testing 3 gallon pots instead of 5. I started off the week by feeling the weight on my plants to make sure they’re wicking sufficient nutrients. I’ve had problems with these wicks clogging. Plant #2 is feeling too light, so I installed a revised feeding base using 1/4 inch wicks to all three plants (instead of 1/6 inch wicks) see photo. I drilled larger holes for the wicks since I believe the rubber grommets used by Vivosun are too small. I’m hopeful that a tweak to the wick design will make these work properly. Fingers crossed 🤞 that this solves the wicking issue. Day 22 Wednesday: topped off water, added .7ml of ph down to each reservoir targeting 6.0ph. 900ppm avg. i believe I’ve addressed the phosphorous shortage, but I don’t know if the leaves will repair themselves or if this is permanent leaf damage. It’s not severe, but it’s worse than I like. Day 23 Thursday: success with the revised wick system for the Vivosun pots. The light pot now has more weight to it, so it’s starting to wick moisture again. Split one gallon of nutrients between three plants. Day 24: Friday the plants each wicked almost one gallon per plant. They were thirsty and making up for lost time with the bad wicks. Spotted a potential potassium deficiency on plant 2. Will watch. Nutrient formula switching back to Heads Formula, so I’ll adjust the feed levels for the week. 6ml of Micro, 9ml of Bloom, 1.5ml CalMag per gallon each. Day 25 Saturday: Topped off reservoirs with RO water. Day 26: Sunday topped off reservoirs with one gallon of Head’s Formula and one gallon of RO water. Plants took two gallons!! They’re really drinking nutrients now that the wicks work. Still some leaf discoloration on plant #1 and plant #2, but I’m hoping the fresh nutrients will restore any deficiencies. Decided that the nutrient burn on plant #2 needs to be addresses. Flushed with 4 gallons of a mild nutrient solution (3ml CalMag, 5ml koolbloom, 650ppm, 6.1ph). First gallon of runoff at 1350ppm. Second gallon of runoff 1150. Final runoff at 975. Vacuumed up runoff then filled reservoirs with 750ppm /6.0ph solution.
