Day 85 - 23.5*C (74.3F), 57% RH. Fed 4.5L @ 562ec, 6.1pH @ 10pm. Feeding later in the day lets me keep the humidity in a decent range without a humidifier - although it's likely not optimal for the plant. Runoff = 1.4L @ 734ec, 6.5pH. Day 86 - 24.1*C (75.4F), 58% RH. Fed 4.5L @ 566ec, 6.1pH @ 9:10pm (Still feeding tap water ph'ed down between 6 and 6.1). Runoff = 1.75L @ 714ec, 6.56pH Day 87 - 25*C (77F), 53% RH. Fed 4L @ 590ec, 6.1pH @ 8pm. Runoff = 1.33L @ 730ec, 6.58pH. Day 88 - 24.4*C (76F), 53% RH. Fed 4L @ 560ec, 6.1pH @ 10pm. Runoff = 1.27L @ 721ec, 6.5pH. Day 89 - 24.2*C (75.5F), 49% RH. Fed 4L @ 550ec, 6.1pH @ 9:45pm. Runoff = 1.28L @ 707ec, 6.5pH. Day 90 - 25.1*C (77.2F), 48% RH. Fed 4.5L @ 365ec, 6.02pH @ 8pm. Runoff = 1.86L @ 707ec, 6.5pH. Day 91 - 24.5*C (76.1F), 51% RH. Fed 4L @ 455ec, 5.95pH @ 4:30pm. Runoff = 1.6L @ 615ec, 6.5pH. Week Summary - Trichomes are still not going amber. This is taking longer than expected but I'm hoping the end product is going to be worth the wait as this is my first grow. Also, the plant has some amazing purplish hue to it - it's mesmerizing and I hope the camera picks up a hint of it.
