leaves yellowing quickly

[revan]

Hello... first time indoor grower and my fan leaves are yellowing and dying rapidly... its day 58 from seed... strain dinafem amnesia auto and royal queen seeds northern lights automatic... buds are healthy as well as leaves around bud but fan leaves, starting from the bottom, have yellowed and died... i know its the natural order of the plants life but i expected this to occur much later... theyre supposed to go 75-85 days but from the looks of things i dou t theyll make it that long... should i flush and go another 2 weeks or so? Any advice would be highly appreciated

Thanks man... much appreciated... iv actually read that b4 but couldnt tell exactly which one it was... but by luck (if u call it luck) 2 of my younger plants started doing the same thing but much slower... yellowing of the leaves but retaining its green, almost like a christmas tree shape, along the "stems" in the leaf... leaves were curling upward so i diagnosed it as magnesium deficiency... upon fixing that problem with the younger plants i realized the older plants had the same symptoms just doing it much faster to the point where i couldn't catch the green christmas tree shape cuz i was always at work and always missed it... so by fixing the younger plants problem i happened to be home to see the older plants in that stage... much help... thanks again
