That girl is beautiful, and really full of nice buds. The reason I asked about the water is if you can fit a plain watering every other time salting-up seems not to be an issue if you get agressive with the bloom nutes. The more nutes I used the more problems I had with ph untill I started the plain water every other time. These autos grow so fast that every feeding is important. If you can let the plant go as long as you can, sometimes 1or2 extra weeks, and feeding, can add more than 20% to the yeild. Anyway when the fan leaves start to yellow, maybe 10days, up the bloom nutes and try and cut out all nitrogen. Check trics often and when the bud leaves start to yellow or the trics are milky/amber (pistols should be almost all orange) harvest. This plant looks like she wants to be a good producer, good luck.
