Auto Northern Lights in coco/perl

Day 57 (day 15 flower) - 24.8*C (76.6F), 61% RH. LST'd two tallest branches. Fed 3L @ 1261ec, 5.98pH (1.2Ca, 1.2Mg, 2.4Micro, 0.9Gro, 3.3Bloom). Runoff = 390ml @ 1443ec, 6.44pH. Runoff vs feed is within 200 so it's fine for now but I might have to lower the feeds if runoff ec climbs higher. Day 58 - 25.3*C (77.5F), 62% RH. Fed 3L @ 1211ec, 6pH. Runoff = 310ml @ 1449ec, 6.42pH. Day 59 - 24.3*C (75.7F), 60% RH. Fed 3L @ 1213ec, 6.08pH. Runoff = 370ml @ 1491ec, 6.47pH. Day 60 - 24.3*C (75.7F), 58% RH. Fed 3L @ 1207ec, 6.1pH. Runoff = 323ml @ 1576ec, 6.47pH. Light is 30.5cm from canopy (12in) (~1033ppfd) (the plant is in a living space so it should be getting more co2 than normal, I'm assuming she might also take higher ppfd numbers than usual). Day 61 - 25.2*C (77.3F), 64% RH. Fed 3L @ 1172ec, 6.05pH (1.2Ca, 0.9Mg, 2Micro, 0.6Gro, 3Bloom) (lowered Mg, Micro, Gro, Bloom by 0.1mg/L). Runoff = 247ml @ 1496ec, 6.36pH. EC difference is 300+ so I'll keep the doses lower and see how the plant adjusts. Trichomes finally started to develop. Day 62 - 24.5*C (76F), 61% RH. Fed 3L (3H later than usual) @ 1136ec, 5.97pH. Runoff = 212ml @ 1518ec, 6.35pH. I might have to fertigate more often since the runoff ec is still around 300 points higher than the feed ec. Ideally I want to keep it up to 200 points higher. Day 63 - 24.5*C (76F), 61% RH. Fed 3L (5H later than usual or 2 hours later than yesterday - meaning the runoff ec/ph numbers are not as accurate as I'd like them to be) @ 1123ec, 6.02pH. Runoff = 210ml @ 1517ec, 6.39pH. Light is 29cm from the top canopy (~1100ppfd) Notes - So far the grow is going good. This strain should've taken ~ 9 weeks from seed to harvest but the vegetation stage was longer than anticipated, maybe because I stressed the plant out in the beginning, maybe its a phenotype that takes longer. I'm not complaining though since the plant looks great. Scent from the trichomes is amazing - sweet but slightly spicy at the same time. They only started developing a few days ago so I'm curious and excited to see what's to come. I'll give it another week or two and then will start flushing. This NL looks great so far - no pest/insect/plant problems whatsoever. I haven't used any IPM tools, although once a week I mopped the floor around the tent with some mint or cedarwood extracts so I'm not sure if that helped. So far I'm happy with this as my first grow ever.
