Still continuing to pluck seeds as they develop. Luckily there haven't been too many and they've been easy to spot. Still unsure on the cause of early browning on the pistils. A buddy of mine suggested it may have been the nutes but I'm pretty sure I saw some brown pistils even before I fed them at 1/4 strength. Going to stick to plain water for another week or so, then try some more Big Bloom and see how it goes.
