Zombie bride by ripper seeds

This is now week 8 and I have stopped all nutrients apart from the power buds and commenced the TA Final Part. Yesterday was 700ppm today 600. I plan working down to just water for her 9th week. Her run off was very high today (Day 52) so I gave her12-15l of flush/feed. I have to say this is by far the frostiest for me so far and I feel I have said that the last few plants. I suspect this is due to me increasing the plant to lamp distance and decreased the strength of feed. I've even started cutting out a lot of components. Things like zyme, silica, carbs and humic/fulvic. I'm not saying they don't help I'm just finding they aren't as necessary as I first thought. They were getting expensive. To me growing in Coco I feel the only ones really needed are a good quality base, calmag on hand, root stim and PK booster on occasion and a bio stim/boost. My light is at 24". It was at 16" and I've kept increasing with increasingly better results . Trichomes on day 52 are observed as follows: 20% clear 10% amber + 70% cloudy. The plan is to chop her on day 63 now after a seven day flush Day 54. The trichomes are maybe now 10% amber 75% cloudy 15% clear. I have started the flush today as my run off was way up. 500 in 3000 out so I will flush longer. She is showing some purple but I am going to wait for a bit more swell, more purple, some fade hopefully and the trichomes at 0% clear 50-70% cloudy 30-50% amber. I'm not in any need for this I have a good amount curing of a different strain. Her smell now is definitely different to what I'm used to. It's normally a citrus smell I've found yet this has a touch of lemon but something of a sweetness. It is familiar but I can't put my finger on it. Familiar not from any previous strain but some smell at the back of my memory. I am going to try turn my central heating off on a night to try induce more colours
