Hello, I hope this isn’t a stupid question, I am a really new beginner. Here goes, white widow auto have been in flower mode now 7 weeks. Branches started turning brown now the main stem is turning brown, top down. Does this mean it’s ready to harvest?
Welcome to the community ! Stems would not relate to time to harvest. You need to get you a Jeweler’s loupe start looking at the crystals, (tric.) On the bud itself not the leaf. Post a picture lots of people here be willing to help you.
She knows the end is near! Like @kellydans says check Trichomes .
