Hey DGC, I am in week 3 of flower and noticed some yellowing of lower leaves and wonder if this is a nutrient or watering issue that I should be concerned with. I am in Happy Frog soil in a 3 gallon fabric pot and let the top 2 inches dry out before watering every 3-4 days. My ppm is currently at around 700, and i’m doing a water-feed rotation with Fox Farm Big Bloom and Tiger Bloom using dechlorinated tap water at 140 ppm. Thoughts?
