Auto Northern Lights in coco/perl

Day 43 - I'll count this as first day of flower since the plant now has 2-4 white pistils sticking out. Temp 24.5*C (76F), 72% RH. Light was 37cm from canopy @ 100% (750+ppfd) so I re-positioned the light to 41cm (~650ppfd). Did some LST. Fed 1.5L @1034ec, 6.04pH. Ive been feeding in the 1000-1150 range and will continue to do so til the plant looks a bit more vibrant green ant healthier and when the tips won't burn anymore. Got 60ml runoff @ 1034ec, 6.66pH - looks perfect. Day 44 - 24.7*C (76.5F), 73% RH. Fed 1.5L @ 1061ec, 6pH. Runoff = 90ml @ 770ec. Day 45 - 24.6*C (76.3F), 73% RH. More LST. Light @ 39cm so I increased the distance to 41cm again since I can see a tiny bit of leaf curling at the top. Fed 1.5L @ 1015ec, 5.77pH. Solution - 0.3Ca, 0.2Mg, 0.6Micro, 0.3Gro, 0.9Bloom / 1L). No runoff. Day 46 - 24.5*C (76F), 66% RH. Light @ 36cm with some canoe action going on so I put the light back at 41cm. Tallest branch is 34cm tall. Main stem cracked from previous LST but it looks like it's healing just fine. Fed 2L @ 1064ec, 5.87pH. Solution - 0.4Ca, 0.2Mg, 0.6Micro, 0.3Gro, 0.9Bloom. Got 72ml runoff @ 1225ec, 6.34pH. Day 47 - 24.2*C (75.5F), 63% RH. Fed 2L @ 1157ec, 5.8pH (increased Mg from 0.2ml/L to 0.4/1L) to check if the stems wouldn't turn so purple since I don't think it's normal for this strain. Got 20ml runoff @1244ec, 6.6pH. Day 48 - 23*C (73.4F), 59% RH ( I want to keep RH in the 55-65% range so I've been lowering it slowly). Light @ 37cm so I reduced the intensity to 85% (~720ppfd) Plant is 38cm tall. Fed 2L @ 1120ec, 5.83pH. Runoff = 23ml @ 1283ec, 6.42pH. Day 49 - 23.5*C (74.3F), 61% RH. Plant looks healthy and a lot better then in pre-flower. I think the increase in Calcium and Magnesium helped. I'll likely be increasing the nutrient dosages next week. Fed the plant 3L @ 1061ec, 6.04pH. Runoff = 555ml @ 1215ec, 6.54pH.
