I faced this problem at the beginning of my journey! It turned out that the problem was solved - by increasing experience))) No more, no less! Only this! Gain experience! And yes, 3 months is a normal standard from seed to harvest! The main thing is not to despair - everything will be !!! Read more, communicate more and everything will come to you! And even faster than 3 months - depending on the variety equipment and experience) good luck!)
