Hey Growmie,
No this is not normal at by Day 47 you should be flowering since this an autoflower. Most autoflowers start showing sex around week 3-4. Occasionally autoflowers forget they're autoflowers and need our help, this is when the grower should switch the light cycle from 18/6 to 12/12 to help the plant start to flower after about a week the plant should be showing sex and signs of it beginning to flower. Hopefully, I answered your question and remember ..."Happy Growing" and "Free your mind one puff at a time".
