Elephant Purple and Scoops 4x4 tent

👉Day 15: All the plants are doing great, they gained about 2 inches last week, I'm guessing 4 more this week. Fed SCPs till it flowed out the bottom of 1.0 EC at 6.5 PH ----Runoff 4.46 EC at 5.6 PH Fed EPs till it flowed out the bottom of 1.43 at 6.5 PH ----Runoff 5.29 EC at 5.7 PH Lights at 70% (315w) @ 2' Temp: Avg 78 High 80 Low 73 Hum: Avg 54 High 64 Low 43 👉Day 16: Biggest SCP is up to 8" biggest EP is up to 9", and everything is looking great. Lights at 70% (315w) @ 2' Temp: Avg 78 High 80 Low 72 Hum: Avg 55 High 64 Low 44 👉Day 17: I'll need to repot soon, the EPs were almost dry already even after being fed to overflow last time. Fed all EPs 750 ml of 1.44 EC at 6.6 PH Fed SCP3 (the biggest) 500 ml of 1.44 EC at 6.6 PH Lights at 70% (315w) @ 2' Temp: Avg 77 High 81 Low 72 Hum: Avg 56 High 64 Low 43 👉Day 18: One of the EPs seems to be having phosphorus deficiency, I'm hoping the next batch will help tomorrow. Lights at 70% (315w) @ 2' Temp: Avg 77 High 82 Low 69 Hum: Avg 58 High 79 Low 40 👉Day 19: More of what I think is phosphorus deficiency visible on the EPs. Removed SCP1 the smallest from the tent, I still have to decide to keep 2 SCPs or go with 1 SCP and 3 EP, the yield I'm sure is going to be less on the SCPs. New mix: Silica Blast: 3ml/g Liquid Karma 7ml/g Cal-mag 5ml/g Pure Blend Pro Grow 9ml/g Rizo Blast 2ml/g PH 6.4 EC 1.43 Fed the EPs 500ml of the new mix each. Lights at 70% (315w) @ 2' Very low outdoor temps causing indoor heat drops especially during dark hours and humidity spikes which triggers the cloudline max humidity setting causing even lower temps. Keeping the lung room warmer seems to have sorted it. Temp: Avg 78 High 81 Low 74 Hum: Avg 60 High 74 Low 46 👉Day 20: SCPs are looking a little sad, some brown spotting on one as well, I think I put off watering a bit too long, we'll see how they look tomorrow after feeding. I think the EPs are doing better under this new mix but hard to say for sure. Fed the SCPs 500ml of the new mix each. Lights at 70% (315w) @ 2' Temp: Avg 79 High 81 Low 74 Hum: Avg 58 High 69 Low 48 👉Day 21: Some more yellowing, whatever deficiency/excess is happening is progressing, I think I should flush but as I'm about to repot, not sure if it should be before or after. Fed the EPs 500ml of the new mix each. Lights at 70% (315w) @ 2' The cloudline wasn't running today despite flashing high temp, hope that's just a fluke and not a defective unit. Turning the control unit off and on again seemed to do it. Another humidity/temp runaway happened during night hours again. Temp: Avg 79 High 86 Low 69 Hum: Avg 61 High 77 Low 46
