ok its getting very close and i am wondering if i should harvest. since its my first time i want to be patiant but they look pretty good to me. i looked at the tricombs but they are so small some of the top hairs are turing redish so i am not sure. its white widow 45 days into flowering in soil. the website says 8 weeks and others say 10. how should i know if i should start flushing?
