Sumseeds Diary 1

Sour diesels moved to grow tent as they proved to be rapid in development. They were first to be germinated therefore up to a week ahead of the hatch. Grow tent uses Bato buckets with drip feed reservoir. Feeding is automated with in-house constructed tuya smart switch system. This system manages feeding/watering cycles using r385 diaphragm pumps. Nutrient dosing is controlled by an array of peristaltic pumps. Water testing is done using a tuya/yinmik 7in1 water QC monitor. It provides real time information and links to wifi so any adjustments can be effected immediately. Light cycle 04:00 to 22:10 at 12k lux (220ppfd) gradual increase to 22.5k lux (400 ppfd). Nutrient solution kept low in drip feed system, feed/watered 8 times per day, 7 minute drip 1 hour periods in morning moving to 2 hour interval, pause 4 hours, back to 2 hours. I may change this schedule to spread the feeding over more intervals with shorter amounts. Had issue when ec dropped to 0.8 (400ppm), one plant started yellowing, ec restored to 1.2, plant recovered with a day. Had some leaf deformity in one of the germination dwc units. The new leaves looked spotted and chewed. At first I was concerned it was thrips and pwm. but now I believe it was a nutrient issue. Applied more CalMag as well as general nutrient top up. These ladies are hungry!
