Hold on just a second. If you are growing from clones the plants are not adapting at all! YOU are adapting to THEIR needs! yes i agree you should focus on one strain at first so that you learn all of its nuances and characteristics. But for a plant to adapt to its environment it takes generations of breeding and A LOT of plants. And it is good to repot plants because it is not a smart idea to start a tiny seedling in an enormous pot: you have a ton of empty, soggy soil which provides a perfect environment for mould fungus insects and other invaders. Yes you are correct that we should give flowering plants some nitrogen during the START of the flowering phase. however it is a fine line, because the best, most crystally weed comes from plants that are completely starved at harvest time. The leaves should be yellow and falling off by that point if you want the cleanest taste.
