Strain in first pic is sunset sherbert the other two I have no idea they were all given to me through a friend haha. Soil is roots organic mixed with super soil no additional nutes except roots organic terp tea grow + molasses. But yeah just been learning as I grow lol.
I looked up the SS and thats a 7 to 8 week strain, so probably more like 8 to 9. Different strains so they'll finish at different times. Just go by the trichome maturity. Can't go wrong that way. Good luck.
