Growing a single Sativa in 5 gal smart pot. Topped several time and supecropped. Feeding nutes, occasional cal-mag, microblast. RO water and mycorrhizae. It's bushing out nice after 4 weeks and I plan to veg 4 more. There is one yellow leaf on it. It will wither and die then one more leaf will turn yellow, wither and die. About six in a row, one at a time. Always the lowest leaf. The rest of the plant is gorgeous. Any thoughts?
