Amnesia Auto & OG Kush in 2x2x4 Tent

SUMMARY: The OG started flowering towards the end of this week which puts it at almost 4 weeks behind the Amnesia. Providing I have no further set backs with the OG I should be able to comfortably meet in the middle come harvest by chopping the Amnesia 2 weeks late and the OG 1 week early. I realized that I had made a mistake in feeding both plants the same schedule as I have caused a nutrient deficiency in the OG as a result. To rectify this I have separated the feeds and started using the updated growweedeasy.com coco nute schedule which is higher doses (double the previous schedule) for the OG. I will continue using the original GWE schedule for the Amnesia as she is doing fine for now. I have noticed that the runoff of both plants has dropped considerably with the OG as low as 5.1. To remedy this I have started giving an input pH of 6.5. DAY 58 -------- Friday 30/10/2020 07:00pm I have realized that the OG is suffering nutrient deficiency and I suspect it is due to underfeeding as it is not an auto, and is almost twice the size of the Amnesia yet I have been giving them the same nutrient schedule (albeit giving 0.5-1.5L more liquid to the OG on average). To rectify this I have separated the feeds for the plants and so each now feed from a separate bottle. The Amnesia is doing just fine and so I will continue using the growweedeasy.com coco coir nutrient schedule however for the OG I have upped the nutrients to the September 2020 revised coco coir schedule on growweedeasy.com which is the same schedule only doubling the nute strength. Updated schedule I am using for the OG as of today:- https://www.growweedeasy.com/wp-content/uploads/2014/12/coco-coir-flora-series-schedule.pdf I gave the OG 5L of Transition nutes from the updated GWE schedule and the Amnesia 4L of mid bloom nutes. Unfortunately I lost the notes I made at the time and I don't remember what the pH of the nutes were or how much runoff each gave but I know each gave more than 20% runoff and the pH of the OG runoff was low at 5.1 and the Amnesia was at 5.8. The nutes would have been pH'd between 5.8-6.2 meaning that the OG has a pH issue as it is dropping by 1 point and is on the acidic side. DAY 60 -------- Sunday 01/11/2020 I spent some time today separating the water and feeds for each plant as they have different requirements in both nutrients and pH. For the OG, I made 5L of transition nutes from the 09/2020 revision of the DTW nute schedule from gwe. Its twice the amount of the previous schedule and I have pH'd it to 6.5 to raise the pH of the coco. The last time I checked runoff before I discovered it was at 5.1 this weekend, was on 24/10 and it was 5.8. For the Amnesia I made 4L of mid bloom nutes from the old schedule as she is doing just fine with nice healthy looking dark green leaves so no need to rock the boat. I also pH'd this to 6.5 as the runoff was 5.8 last time I checked (24th oct) and I'd like it at 6.0 ideally so its bang in the middle. OG (IN) = 5L pH 6.5 OG (OUT) = 1.8L (36%) pH 5.5 [1.0 drop] Amnesia (IN) = 3.5L pH 6.5 Amneisa (OUT) = 1.5L (43%) pH 6.0 [0.5 drop] I will keep feeding both at 6.5 until the runoff stabilizes around 6.0 at which point I will lower to 6.1 intake. I gave the OG 4L of transition nutes from the revised GWE coco coir schedule above and the Amnesia 4L of early bloom nutes from old GWE coco coir schedule. The Amnesia should be on mid bloom nutes now as of today however I had exactly 4L of early bloom nutes pre-made and so I gave it that for today. The OG gave 600ml runoff (15%) at a pH of 5.1 and so the pH is off as suggested by someone responding to my grow question on here. I check the pH once per week and so this has only fallen out of range in the last 7-10 days and so I do believe it is also a case of nute strength being too weak. To rectify this I will up the pH of the feeds to 6.5 until its back in range. Although 15% runoff is too little I will not increase the amount above 4L just yet as 4L every 48hours seems a lot. The Amnesia gave 1700ml runoff (42.5%) at a pH of 5.6. I will also raise the pH of the next feed to 6.5 and only give it 3.5L of mid bloom nutes. With this now being the 4th week of flowering for the Amnesia and the OG has not yet even started to show pistils, I don't think I'm going to be able to harvest the OG as they both will need to be chopped when the Amnesia is done. DAY 62 -------- Tuesday 03/11/2020 Both plants were due water and so I gave the OG a flush with 5L of rainwater pH'd to 6.5 and gave the Amnesia 3.5L pH'd to 6.2 (I meant to do 6.5 but forgot as I'm an idiot). The OG gave 1.75L (35%) runoff at a pH of 5.2 and so is still a drop of over 1 point and the Amnesia gave 800ml (23%) at a pH of 5.7 which is 1/2 a point drop and is fine and can be expected - it is also within the correct range (5.5-6.5) for coco. OG (IN) = 5L pH 6.5 OG (OUT) = 1.75L (35%) pH 5.2 [1.2 drop] Amnesia (IN) = 3.5L pH 6.2 Amneisa (OUT) = 800ml (23%) pH 5.7 [0.5 drop] I prepared nutes for the next feed with 5L of (revised GWE schedule) transition nutes at a pH of 6.5 for the OG, and 4L of mid bloom nutes (old GWE schedule) at a pH of 6.2 for the Amnesia. As the Amnesia runoff is at the low end of the range I will pH the Amnesia feed up to 6.5 tomorrow as I had originally planned before its next feed on Thursday. The OG is FINALLY flowering! Its also done some stretching and is now twice the height of the Amnesia. I was getting concerned I was going to have to just throw it but I'll let it run as long as possible (Amnesia harvest will dictate) and maybe I'll be able to make some butter or something - If I'm lucky the buds might have fattened enough to make it smokeable though with the Amnesia strating to flower on it is weeks behind.
