clovisman Reviewed by clovisman on . Flowering and yellow leaves In flowering for 4 weeks. Buds look great on the Indica. One plant of unknown chronic has developed a yellow leaf issue. The yellowing is on the very bottom leaves and then some in the middle. Is this normal at 4 weeks with some strains? Rating: 5
