Question this is my Blueberry auto from Ilgm day 68. When should I Flush nutrients from her. She is hydroponic in clay balls. I see the pistils are turning brown slightly. Tricomes are appear clear. Ph 5.9 ppm about 850ppm. Using Fox farm big bloom and tiger bloom. 3tsp to 2 tap/gallon. How much longer?
Most my autos take 90 days or so. You are looking at about 22 days +/-. Flushing nutrients takes 10-14 days. I usually start flushing out nutes from my soil grow once the trichomes reach maturity. (All cloudy). I like amber trichomes so this time works for me. If you want no amber start when the trichomes are 50/50.
Skipped the Grow Big for a reason?
That is a hard question to answer but Id say your looking at AT LEAST 3 more weeks.
After most of the pistils have turned orange and receded into the buds start checking trichromes. If you’re doing a final flush then do like @Docnraq said. My two auto grows took 104 and 107 days to finish so hang in there.
