Gorilla Girl, Sweet Amnesia Haze, TPF1FV

Day 15. CLA temps 21-27C, roots 22-24, RH 48-70% EC in the res had risen to 0.77 which is a usual rise the day after adding a mix. On first opening the tent air temps were 26C, leaf temps 23C and RH 55%. I checked the VPD from these stats and this gave a reading of 0.96 kPa which is in the middle of healthy transpiration for late veg/early flower. All well and good if my infra red thermometer reads correctly (I think I knackered it making ISO oil and pointing it into the boiling fumes lol). I had hung my hygrometer in the canopy of the GG on day 13 and thought that was the reason for the spike in humidity on the day 14 readings, but since moving it back to the side of the tent the RH high on day 15 was the same so that's where the hygro stayed. The spike in humidity was from the lower air temps. Day 16. CLA temps 22-27C, roots 23-24, RH 47-65% EC in the res 0.77 It suddenly dawned on me that the nights had got a bit cooler again and RH was still quite high so I turned the oil rad back up from 5 o clock on the dial to about 2/3rds to keep things sweet. Day 17. CLA temps 22-27C, roots 23-25, RH 42-58% Looks like turning the rad up sorted the RH out but only kept the temps steady as they were, no rise. Mixed up a quick 5L of feed as work was getting in the way of things a bit. Background EC straight from the tap 0.35 1/2 ml/L MC to 0.4 1/2 ml/L VK to 0.42 1/2 ml/L Mi to 0.49 1/2 ml/L Bl to 0.56 1/2 ml/L NC to 0.6 1/2 ml/L AF to 0.64 Added the mix to the res. I couldn't check the res EC beforehand or the combined EC after topping up. I'd gone up there in pitch black at lights off and got my bottles, EC pen and water container to mix downstairs, then went back up and topped up the res in the dark. After 12 hours the res EC was 0.78, much the same as the previous day. Day 18. CL air temps 22-27C, roots 23-24, RH 45-56% EC in res 0.79 Checked the current stats as soon as I opened the tent for a VPD check. CL air temps were 27, leaf temps 25 and RH 52% which gave a VPD reading of 1.31 kPa, which falls into the band for high transpiration rate for mid/late flower. A bit high for early flower, but at the lower end of the band and heading in the right direction as far as I understand it because they'd be entering mid flower soon. Mixed up 20L of feed. Background EC 0.39 (stood for a day) 5/8 ml/L MC to 0.46 5/8 ml/L VK to 0.49 5/8 ml/L Mi to 0.57 5/8 ml/L Bl to 0.67 5/8 ml/L NC to 0.72 1/2 ml/L AF to 0.78 Added to the res for a total of 29L and combined EC of 0.79 I'd lowered the Astro Flower a touch, as the leaf tips looked to be burning a bit. I had to turn my veg cab extraction up a touch to improve conditions in there, so turned the fan running straight from the rad box down a bit to compensate and maintain negative pressure in the tent. (I have two 4" fans supplying a 6" splitter into my tent. One draws straight from the rad box and the other draws from the rad box via my veg cab) Day 19. CL air temps 22-28C, roots 23-24, RH 45-59% EC in res 0.85 There were 23L left from the previous day's 29L so the girls were still drinking an average of 833ml each daily across the total of 6 plants in there. I added a further 1/4 ml/L of both MC and VK to the 23L, which raised the EC to 0.92 and then set about spreading the Gorilla Girl out a bit. Day 20. CL air temps 22-28C, roots 23-25, RH 42-60% EC in res 0.89 On opening the tent air temps were 27C, leaf 22 and RH 46% which gave a VPD reading of 1kPa and is bang in the middle of the healthy transpiration band for late veg/early flower. I'm not that bothered about VPD as I can't really control all 3 factors that well with my basic DIY set up. But this reminds me that I should try and get the leaf and air temps up a bit while lowering humidity a touch as they go into mid flower, and move the VPD into the high transpiration band for mid/late flower. Like I said though, I'm not that cut out for it and I'm not sure the IR thermometer is accurate. As long as my girls are growing healthily and humidity isn't too high I won't make any big changes. Day 21. CL air temps 22-28C, roots 24-25, RH 44-57% EC in res 0.89 Week 3 stretch. Gorilla Girl: Flip = 16". Day 7 = 19". Day 14 = 25". Day 21 = 29". Total stretch = 13". Sweet Amnesia Haze: Flip = 15". Day 7 = 18". Day 14 = 22.5". Day 21 = 26". Total stretch = 11". Tropicanna Poison F1FV: Flip = 22". Day 7 = 27". Day 14 = 28". Day 21 = 33.5". Total stretch = 11.5" minus the plant bend training. Looks like rooting the final pots out for 3 weeks before flip and keeping night/day temps as close as I could worked ok for me again. The GG stretched x 80%, SAH x 70% and TP x 60% with the added training. Happy with that :) the TP would have been too close to the LED by now if I hadn't used the plant bendz. I only just got away with it really, as the stems were too rigid to bend them again. She's solid. The LED was still set at 115w on the blue and I turned the far red up to total 125w.
