Started flush on Day 108. 4 liters of Flawless Finish solution, with an 10 hour soak. Followed by a 30 liter flush. EC runoff knocked down to 0.8. Day 112 she is starting to get purple. A further 6 litres of straight ph'd water. Harvest should be next week :)
Good luck with the grow. I'm on week 10 of my first grow with two sensi-seeds northern lights feminized, and the plants are doing really well.
I hope yours do the business also.
