August 28, day 118 (day 51f), I have been flushing with tap water and a little florakleen for the past few days, and will harvest soon (within the next 3 days or so). The plant is definitely ready, with the overall yellowing, cloudy trichomes, and orange pistils.
Will turn off the Mars Hydro SP-3000 a day or so before harvest for a final dark period. It has been a champ for this grow.

Mate, you have acid in soil due to exces perlite dust and I had also that kind of issues so now I only use soil and baltic peet and no verm. or perlite mix for me any more. Keep the good grow. ๐ค๐ค๐ค
