Durban Poison SCROG SIP (Sub Irrigated Planter)

Welcome to week 3 of veg. They’ve been growing about 1” per day lately. I’m planning to SCROG these three girls with a portable scrog screen. Supplies arrive today and I’m anxious to test this. (Note that my portable scrog screen didn’t work, so I’m using a 2x4 stretch screen). So far the self watering feeders are working well. The reservoir ph does tend to climb, so I make regular adjustments by adding RO water to the nutrient mix and using ph down. The PPM of the nutrients is climbing too, so adding RO dilutes that. As an example, it had climbed from 925 ppm to 1080 ppm overnight. I diluted it back down to 880 ppm. Saturday: installed scrog net Sunday: checked reservoir ph (6.4) and ppm (970). Added ph down. Adjusted scrog net. Discoloration in leaves appears to be worsening. Waiting for a new dehumidifier to arrive. With all of the humidity that the fiber pots put off, I’m going to need a dehumidifier in flower. Monday: ran pipes for humidifier, heater and dehumidifier through a different tent outlet. I’m ready to start dehumidifying at flower flip. Removed humidifier since I won’t need it until after the harvest (I dry in my tent ideally). Topped off reservoir water with a heavy emphasis on CalMag. Reservoirs are at a ph of 6.0 and 750ppm. Lowered ppm due to start of burnt leaf tips on one plant. Wednesday. Lowered ph in reservoir from 6.4 to 6.1 with ph down and diluted nutrients. Lowered ppm from 780 to 700. Removed growth below the SCROG net. Adjusted lighting to a DLI of 35 which proved too intense for the plants, so I backed it down to 30 DLI. Thursday: wrapped up the week by giving them a foliar spray after lights went out. Feeding 5ml/g or CalMag and 30ml/g of Seaweed Extract. Topped off reservoirs using 6ml/g of micro, 9ml/g of Bloom, Seaweed and 2ml CalMag.
