NYC Diesel Closet Grow

I spent the week looking at trichomes until yesterday when I decided they look about right to me. The top buds are definitely looking ready but I've also kept a close eye on those in the middle. I began with a regular watering of clean pH'd water until my new TDS meter delivered today. Ended up doing to 3 gal flush to bring the ppm down to reasonable levels. Will continue with feeding only water for the next few day until harvest.
