Organic Gorilla Glue Auto x2

Oct 9 - Noticing beginning of fade! Both plants are gaining mass in main cola, with one lagging on trichome development. Days are 20F colder, which makes managing optimal temperatures easier inside the tent. Will aim to water at 4PM Oct 9 - Noticed the first Orange hairs appearing on on of the lower colas. Touched the trichomes accidentally on main cola - worried that THC is gone forever. Oct 10 - Noticed rust spots on one of the plants leaves - Likely magnesium deficiency, I'm hoping it's just a symptom of fade (but likely incorrect and is a larger problem). Watered .7L at 5pm. I noticed some flakes of paint in the dechlorinated water. Hoping this doesn't affect the plants. Oct 11 - Leaves are transitioning from darker green to lime, thankfully the calyx' are starting to gain volume on both plants, though one trichome developments is much lower. Scent is still very mild, though sour aroma lingers on the fingers post contact. Oct 11 - Watered at 5-6PM 1.1L (stepping up from .7L) to see if they'll fatten up accordingly. I hope this doesn't result in soggy soil same time tomorrow. Oct 12 - Checked night time temp and RH. Temp is 62F and RH is 49%. Up to 75F within 2 hours of lights on Oct 12 - Noticing more red rust spots spreading, though leaves are also yellowing just as calyx' are gaining mass. Added another Oscilating Fan to aid in penetrating bushy foliage. Oct 12 - Watered 1.1L at 6-7 PM. Plants seem okay with increase in water, perhaps 1L each is enough. Oct 13 - Noticing pistils are turning colour to a pale orange. Oct 13 - Watered 1.2L around 8-9PM (26+hours since last water). Aiming to keep temperature under 75F from now on. Oct 14 - Noticing more red spots. Might double check PH calibration. Watered at 12.30-1 AM - 4 hours overdue Oct 15 - RH at 60% after 5 hours of darkness. Dropped to 37% after 10 minutes. Hoping this hasn't started bud rot. Trichomes are slowly developing on both plants. Lower bud-sites are super airy, with very little calyx volume in contrast to top colas. Oct 15 - Inspected most large buds and no whispy white, brown or discoloured buds so far. Oct 15 - Watered only 1 plant as soil was still too moist from last midnight. Could be a sign they're getting close to finishing too as pistils/stigmas are roughly 30% Orange. Oct 15 - Re-Calibrated PH. Water was reading at 8.13 - 8.10 before calibration. After calibration reading of same water was 8.06 - 8.02. PH was off by roughly +0.05.
