I know that it's just to much to type im always in such of the Emerald forest mostly Indica strains just to many to list my main start of my breeding line males blueberry kush ,GSC ,Bubba Kush,Bannan kush, those are most of start but always on the look out.
I don't grow for flower I grow for seed production but in the past yes we grew a gram a watt easily there is a lot of factors to consider but easily 2.5-4 I've a plant not autos there in a different category altogether
Sprayit right up till you see pollen on a leaf if you don't you will have banners with nothing in them you also don't need the week before flower and some strains reverse very easy with lots of pollen some don't if it don't work just try it again
Lst training can be started as soon as you fell that the plant is strong enough to handle it and there is not much help to the plant stressing it out at such a young age you should try to wait tell you have 4 - 6 node spacings the plant would be strong enough.
