Amnesia Auto & OG Kush in 2x2x4 Tent

SUMMARY: Turns out the OG Kush is a photoperiod plant and so I flipped the lights to 12/12 this week to start it flowering. It's already 2 weeks behind the Amnesia and so if it doesn't start flowering soon I will run into issues come harvest time for the Amnesia as I only have the tent for growing and drying. The Amnesia is drinking roughly 3.5L every 48hrs whereas the OG is requiring around 4-4.5L. DAY 52 -------- Saturday 24/10/2020 06:30pm I gave the plants some early bloom nutes, 5L for the OG and 4L for the Amnesia. The OG gave roughly 1400ml (28%) runoff at pH 5.8 and the Amnesia gave roughly 1200ml (30%) at pH 5.8. So the OG is sadly and clearly a photo and so I flipped the lights to 12/12 today to start it flowering so hopefully it wont be too far behind the Amnesia. I'll just have to cook the amnesia a couple weeks late and chop the OG a week early or something like that. DAY 53 -------- Sunday 25/10/2020 Made 10L of early bloom nutes at 6.1 pH DAY 54 -------- Monday 26/10/2020 06:30pm I gave each plant 3L of nutes. I intended to give them 3.5L each but saw runoff after only giving 2.5L and so stopped at 3L. The Amnesia gave just over 800ml (27%) runoff whereas the OG only gave 100ml (0.3%). I'm not bothered enough to give extra to the OG and so will just ensure it gets at least 3.5L next feed. The OG is going to get too big for the tent I think. I'm hoping they dont have the same growth spurt the autos have when entering flower otherwise I've got problems. I have tied down around another 4 shoots on the OG which are climbing but I have more vertical space than I do horizontal and so I think Ive done all I can now for training them. DAY 55 -------- Tuesday 27/10/2020 I made 5L of early bloom nutes with rainwater to pH 5.7 [24°C/55%] DAY 56 -------- Wednesday 28/10/2020 06:30pm I gave the plants 3.5L of pH'd water each. The Amnesia gave 1400ml (40%) runoff and the OG only gave 300ml (9%). The OG is still not showing any pistils which is worrying because I'm already pushing the difference between them as it is and I only have the one tent. I will just have to run the Amnesia as long as possible and then just chop the OG when the amnesia is done no matter where the OG is up to. I've noticed some nice purple stems throughout both plants which made me realise that I have been giving the plants very cold water every feed as the water sits in the shed which is essentially outside. I will have to store the water indoors moving forward.
