no problem, don't get me wrong though it may take up to 90 . I've seen some grow journals that went past 100 days. the thing is to watch your plant and she'll show you, when those fan leaves start turning is the indicator. I got that info from a good autoflower resource Google afn and you'll find it. I think my girl is going to be on that long day count. I may steal a little from her lol if she's not ready by 4/20 haha.
