Girl Scout Cookies (Garden of Green)

I'm starting a mini flush this week. I replaced about half of the nutrient solution with plain water, which lowered PPM to the 700s. I'm planning on letting her consume whatever nutrient solution remains until red/amber trichomes start to appear. At that point I'll perform a full flush with RO water for a few days then harvest Currently the trichomes are mostly clear which is why I'm waiting on the full flush. I've started to see some leaves yellow and hopefully a lot more by end of week. Overall she looks and smells great. Looking forward to the harvest
