How much longer?

Lit Marker has a flowering time of around 70-75 days. If buds are still getting bigger then it's not time yet. Most of the pistils should be amber and curling. Water uptake will decrease also. Make sure to look at the actual buds and calyx, leaf trichomes mature faster. I like to harvest based on if it's a Indica, Sativa, or balanced Hybrid. When the bulbous heads of the trichomes are fully developed but still translucent, plants will produce a "high" and stimulanting effect, less sedative. It is the perfect moment to harvest strong Indica strains. When these bulbous heads turn milky is probably the best moment to harvest most available hybrids. When 70% of these trichome heads are milky and 30% amber, it is the perfect time to harvest mostly Sativa hybrids and long flowering strains (like Haze).
