I think the yellowish...is that a word. anyways the yellowish I think is from being inside the greenhouse and not getting as bright or strong UV as what the outside plant gets in the open sunlight.Every time I over water a plant it droops and if uptake shuts down long enough chlorosis sets in. Never a droop. Just a plant with lime leaves. In 3 gallons of soil and at 44" she may just need more juice(nutes, not water, lol). And the yellowing may be fall fade.
Cannabis plants and with all plants really don't matter which plant you look at they protect themselves with the brighter colors against the UV it's a defense mechanism.
I would say that you're going to experience between those two exact strains that the one growing outside is going to have a little more flavor and more stickiness or resin, trench or whatever you want to call it than the plant on the inside under the greenhouse top. Again that's just because it's a defense mechanism against the UV.
