Amnesia Auto & OG Kush in 2x2x4 Tent

SUMMARY: Due to time constraints I decided in the end to make this the last week. I checked the trichs on both plants and the Amnesia now has plenty of amber heads and the OG now also has some albeit much less. Though all trichs are at least milky with the exception of the rare clear head or 2. I did a quick flush watering with rain water only on Monday, Tues, and Thursday then left to dry until Saturday when I chopped them down. DAY 92 -------- Thursday 03/12/2020 I fed the plants. GWE 04/2020 updated schedule Week 9 Late Bloom nutes for the OG and then the Sensi Garden Peak nutes for the Amnesia. OG (in) = 5.5L pH 6.5 OG (out) = 0.6L (11%) pH 5.6 [0.9 drop] Amnesia (in) = 3.5L pH 6.4 Amnesia (out) = 1.6L (46%) pH 5.8 [0.6 drop] If my eyes don't deceive me it would appear that the Amnesia is finally starting to pack on some weight! Hopefully both will have a decent yield in 2 weeks time. The RH has been at 45-48% for the last week and the temps are consistent at 24°C and so we're right on track. DAY 94 -------- Saturday 05/12/2020 I fed the plants though gave the amnesia less volume as it doesn't need it. GWE 04/2020 updated schedule Week 9 Late Bloom nutes for the OG and then the Sensi Garden Peak nutes for the Amnesia. OG (in) = 5.5L pH 6.4 OG (out) = 0.4L (8%) pH 5.3 [1.1 drop] Amnesia (in) = 3L pH 6.2 Amnesia (out) = 1L (33%) pH 5.6 [0.6 drop] The OG is drinking more and more and both plants are definitely starting to pack on some weight now and I'm very excited. DAY 95 ------ Sunday 06/12/2020 I checked the trichs on both plants and its a good job I did as the Amnesia has plenty of amber heads (possibly upwards of 30% its very hard to confirm tbh as the usb microscope is handheld and so VERY sensitive to movement - it took me best part of 30mins to get enough clear shots for me to decide the Amnesia is done). I took shots of both trichs using my usb microscope but as its cheap and the app is freeware it is awful and so just clumps all your pics together and not in any particular order, or at least not in the order they were taken and so after spending 30mins+ taking pics I don't know which are from which plant! But both have amber trich heads showing though the OG doesn't have as many as the Amnesia as expected. I wasn't going to do a flush after doing some research and seeing that its a controversial topic over whether there is any benefit and my rationale being that I'd rather the buds be as big as possible and so it made sense to feed up until chop. However I changed my mind after not being able to find a reputable source that claims flushing is not beneficial plus the general consensus is that you absolutely must flush if using synthetic nutes which I am. I will flush from now until Friday and then chop on Saturday or Sunday. DAY 96 -------- Monday 07/12/2020 I watered with rainwater (pH between 6.2-6.4) giving the OG 6L and the Amnesia 5L to ensure plenty of runoff. DAY 97 -------- Tuesday 08/12/2020 I watered with rainwater (pH between 6.2-6.4) giving the OG 6L and the Amnesia 5L to ensure plenty of runoff. DAY 99 -------- Thursday 10/12/2020 This should technically be week 15 as of today but as I'm chopping on Saturday its just not worth creating another flowering week in this diary. I watered both plants for the last time today, both with rainwater (pH between 6.2-6.4) giving the OG 6L and the Amnesia 5L to ensure plenty of runoff. I will now let the plants dry out until harvest which will be on Saturday 12th. I have also knocked the lights off to leave them in darkness now until chop which gives them roughly 40 hours of darkness as advised by many. Apparently the darkness can somehow increase the potency though it seems this is another controversial topic and one I haven't done enough research on and so have decided to do so as all the tutorials/guides/diaries I've read do 12-72 hours of darkness before chop. If I don't chop this weekend then I'll be pushing it if I want another harvest before I go away next year. If this wasn't the case I would let these run until the Amnesia was about 50% or more amber to give the OG time to catch up as the OG genetics are much superior to the Amnesia.
