yea the fan leaf stems are taking a maroonish color...and i just fixed the light problem...i got 3 26 watt cfl lights around it...one hanging above and 2 giving light from the sides.Wat does the coloring of the stems mean
I dont think you can tell about the type till it buds then you can mostly tell by the smell and tast of the plant. And about the coloring I have no clue lol but thats cuz im a starter in growing.
also when they do start budding if you want to know by just looking i have and are going to improve a page on my site called types of marijuana. and for beginners like me iv got a beginners guide to growing marijuana.
