First "Living Soil" Run (Gelato Auto)

Day 22 -Start of week 4! Watered each plant with 6 cups of pH balanced water. Day 25 -Watered each plant with 6 cups of pH balanced water. Water was dosed with 1tsp of Recharge. Day 28 -Watered each plant with 8 cups of pH balanced water. Had some runoff...not alot but I've heard it's bad with organics, since it leaches from the soil. So I let each plant soak up the cup or so of runoff. Also running into some discoloration on some lower leaves. Rest of plant is healthy, so I'm wondering if I should top dress with my bloom nutes now? It could just be because both plants are so bushy, it's just dying because lack of light. I dunno. ---Also changing this week to flowering as she started flowering super heavy around Day 25ish, and is rapidly stretching and getting bushier.
