ZkittleZOG Auto Greenhouse Barney's Farm

Week 10 - stopped feeding and started to flush, (after the issues my other girls I do not want to ask lightning to strike three times)... Barney's Farm harvest target is 70-77 days.. She just hit day 70 and even to my untrained eye she doesn't look anywhere near ready... am flushing every three days, (it has been especially humid) and giving her about 8 liters split across two waterings - she is putting on weight,.... will keep an eye on things pistils and trichome development; have also decided to leave her to dry for a few days at the end of the flush just so that she isn't carrying too much water into the dying (hanging stage).. so it could be an 84+ day harvest - as mentioned the weather has been funky which I guess is impacting her ability to fill out and get really ripe, generally it is very humid (in the greenhouse at night) even with dehumidifier running.. so the conditions are not optimal and my set up is not exactly pro. Just learning and adapting as the days go by. She is covered in sugar, at night under torch like she looks like she is covered in a beach of diamonds! Smell is starting to come through, a quick rub of a sugar leaf and she is sticky and the aroma is very fruity.... Quick question - I have noticed on some of the indoor grows that the leaves really fade out as the plant uses up all remaining nutrients within the root system/soil, does this also happen with greenhouse/outdoor grows - with it simply being a matter of time playing out, or is it due to using indoor lighting systems?
