First autoflower

Today marks week 9 of the red poison auto flower. I started the flushing process this week. The Trichomes were starting to get milkiy on week 8 so I decided to flush the plant since I am looking for 65 to 80 % of milkiy for my final product. I am going to flush for 2 week for the best results (in my opinion) since the medium I am using is soil. Instead of feeding her nutrients on October 16 2019 I just gave her the 1.5 gallons of PH(FOR SOIL 6 - 6.8) water with molasses.. I checked the run off water and the PH was 6.8 and my PPM was high at 1336. So on October 19 2019 I did a extreme flush of my auto in a 7 gallon soil pot. (I have tried flushing with certain agents in the past but from my experience and opinion I feel that flushing with just PH water works fine.) Well I flushed the plant down from 1336 to 336. I would have preferred a PPM level below 200 but the water I am using has a PPM level of 270. I actually ended up using 18 gallons of PH water to flush the plant in order to bring the PPM down from 1336 to 336. The PPM kept kept going down and then back up again after every flush so I had to keep adding gallons of water in order to make sure that at least half of the nutrients were washed from the soil. From this point on I will no longer feed her nutrients. I will just give her the regular amount of PH water I've always given her except the only difference is that I will no longer add nutrients to the water. The only thing I will add is molasses in the PH water in her regular feeding schedule. I am hoping to harvest around the 26 of October.
