Amnesia Auto & OG Kush in 2x2x4 Tent

SUMMARY: The plants have responded very well to the increased frequency of irrigation and so I will now continue with only giving a plain watering every 3rd watering. The OG is consuming more and producing less runoff and so I have upped the intake to 3L per watering though the Amnesia is getting along fine with 2.5L intake and producing 20% runoff. The temps have exceeded 30°C again this week which may have caused the plants to drink more and some leaves are showing signs of stress and though I cannot determine exactly what the cause is I suspect it is heat stress/nute deficiency. My theory is that the increased heat is causing the plants to drink more which in turn looks to be causing a nute deficiency on the OG as it is a little on the pale side. DAY 31 -------- Saturday 03/10/2020 08:00pm I made 10L of nutes up, 5L at pH 6.0 and 5L at pH 6.1. The plants have responded VERY well to more nutes and have both grown quite a bit in the last 48hrs. I will definitely only be giving plain water once every 3 feedings to increase the nutrient intake. I think I have stunted their potential a lot by under feeding. The plants were due a watering and as usual the coco was still a bit damp up to 1 finger deep. I gave the OG 3L of water (250ml runoff = 8%) as I was seeing any runoff, and have the Amnesia 2.5L (500ml runoff = 20%). [25°C/57%] DAY 32 -------- Sunday 04/10/2020 08:00pm The plants were only watered yesterday and the coco was still damp up to 1st knuckle (length of forefinger) but as I want to increase the nutrient uptake I have given each 2L of week 3 strength nutes. The Amnesia gave 850ml (40%) runoff at a pH of 6.0 and the OG gave 1L (50%) at a pH of 5.9. There are some signs of an issue with the OG that I will closely monitor the next few days to ensure it is not spreading. Small spots of browning on a couple of the higher leaves and some slight burning of the tips that might indicate nute burn. Seeing this and still feeding them today may be seen as not a smart move however if the issue persists I can then be confident that the issue is nute burn as it only started since I upped the nutrient intake over the last few days and all other conditions are on point. I will be surprised if it is nute burn though as the schedule I'm using is very mild, particularly when compared to most schedules I see people running. [25°C/55%] DAY 34 -------- Tuesday 06/10/2020 05:30pm The plants were due a watering as they have had nutes the last 2 times and so I gave them each 2.5L of pH'd water. The Amnesia gave 300ml runoff (12%) and the OG surprisingly gave off 1L runoff (40%), pH of runoff not taken. There is some damage to some of the leaves on the OG. If I didnt know there were no pests/insects in the tent I'd assume it had been eaten by looking at it. There is also some nute burn on some of the tips of the OG leaves and so it seems the OG is more sensitive to nutes than the Amnesia which shows no sign of nute burn. [28°C/60%] DAY 36 -------- Thursday 08/10/2020 08:00pm The plants were due a feed and so I gave them each 2.5L of week 3 strength nutes as that's all I had prepared but I noticed that the plants have now started flowering as there are many pistils forming. I didnt see any pistils last time so this must have occurred in the last 48hrs. I gave the plants 2.5L each but perhaps should have given only 1.5L as I intend to feed them again tomorrow with the "transition" stage nutes from my nutrient schedule as they are now flowering. Interestingly both plants gave zero runoff and they were very light before feeding and so I'd say their needs have increased, though perhaps it's just due to the growth spurt they go through as they transition into flowering as I know this happens and they use a lot of nutes during this time whilst they stretch. Both plants are showing signs of nute burn but the Amnesia looks to only show it on 1 or 2 leaves whereas the OG has quite a few leaves affected. The tent temperature has been very high the last couple of days with an average of 30°C and a high of 33°C which isnt good. Though this explains why the plants were so light as they will have drank more. [30°C/50%]
