Amnesia Auto & OG Kush in 2x2x4 Tent

SUMMARY: I have removed the first 2 leaves from each plant as they were dying/dead. I have continued with the LST aiming to have the plants reach out to the edge of the pot and then eventually spiral around the pot to keep the height under control. The average input volume is still 2.5L though I increased this to 3L towards the end of the week as the runoff volume decreased. The runoff pH has climbed to the high end of the advised range (5.5-6.5) with the OG actually giving a runoff pH of 6.6 and so I started reducing input pH to 5.8. DAY 24 -------- Saturday 26/09/2020 08:30pm No further training required yet, the plants haven't grown enough yet, though I have readjusted the ties to ensure the plant keeps growing into the desired shape as the ties had slid/moved slightly. I removed the first 2 real leaves from the OG that had died off and I inadvertently nicked one of the new growth stems down below and so I will have stunted the growth slightly but nothing it wont recover from. Plants were due a feed and the pots felt light with coco only slightly damp 1 finger deep. I gave each plant 2.5L of week 3 strength nutes. I waited around 20mins then checked the runoff. The OG gave no runoff at all so need to keep my eye on her as her requirements have gone up. The Amnesia gave 200ml runoff at a pH of 6.3 and so both plants are now consuming more per feed. [23°C/55%] DAY 25 -------- Sunday 27/09/2020 08:00pm Coco still damp 1 finger deep so no watering. Adjusted the ties again on both as they are both growing daily though no new ties required yet as no new tops yet formed. [23°C/57%] DAY 26 -------- Monday 28/09/2020 08:30pm Both plants due a watering and they felt light with coco mildly damp 1 finger deep. I gave each plant 2.5L over the course of 5mins but no runoff so I increased to 3L then saw run off from Amnesia but none still from OG so I slowly kept giving more to the OG until I saw some runoff which ended up being 4.5L in total. The Amnesia produced 800ml runoff (27%) at a pH of 5.8 and the OG also produced 800ml runoff (18%) at a pH of 5.8. I need to ensure I keep the water and nutes at a min of 6.0. I adjusted the ties to the OG and added more to bend her to grow around the pot now she has reached the edge of the pot. The Amnesia is not growing as fast and is very short and bushy and so I ran a piece of wire from one side of the pot to the other to rest some of the lower leaves on to expose them to more light. [27°C/58%] DAY 27 -------- Tuesday 29/09/2020 08:00pm The plants weren't due a feed but as the third week is nearing an end I feel they are behind on irrigation and so I decided to feed them as an experiment as they had plenty of water yesterday. I gave each plant 2L of week 3 strength nutes at which point I could already see runoff. I left it it 30mins before collecting the runoff but didn't pH the runoff tonight as I don't have time and I only checked the other day. The Amnesia gave about 1L runoff (50%) and the OG gave about 900ml (45%). I don't think they are quite there yet in regards to needing a watering/feeding every 24hrs. I also adjusted the LST on the OG again ensuring that it is now following the shape of the pot. The Amnesia looks to be growing the same rate almost, definitely a little slower, but its just so compact. Its becoming difficult to water without touching the leaves and I got some nutes on some leaves and had to wipe of gently with my fingers (no tissue to hand). [27°C/55%] DAY 29 -------- Thursday 01/10/2020 08:30pm I didn't feed or water the plants yesterday as they had plenty on Tuesday night (day 26). The plants have responded well to the nutrients from Tuesday which makes me think I have been underfeeding them and so I am taking the advice of someone from a grow community on reddit who used the exact same "Grow Weed Easy" GHE nute schedule and advised the PPM was very low and the grow was slow going and so he upped the feedings by only watering once or twice per week and feeding 5 days per week though his were in 1gal pots (he also upped the grow and micro by 1ml per gallon which I won't be doing). The same person also advocated switching to "the Lucas formula" at around week 8 for better yields. The coco was still a bit damp 1 finger deep but plants were due a watering as per schedule however with the above in mind I fed them again with week strength nutes. I only had 6L of nutes premade and so I gave the Amnesia 2.5L and the OG 3.5 as it tends to drink more being bigger. I then left the plants for 30mins before collecting the runoff. The Amneisa gave 600ml runoff (24%) at a pH of 6.4 and the OG gave 1L of runoff (29%) at a pH of 6.6 and so I need to ensure the pH of my water and nutes is always 5.9-6.2. [26°C/55%]
