Hello, guys! I have trying to grow for a year now, first time was a disaster with over supplementing and "burning"my plants with nutrients which did not yield anything. Second and third time i had some results with autos. Now i switched to other auto strain. After 2 months i had healthy plants, but no buds! I red that it can be possible because of "bad genetics" and some had luck with switching to 12/12 cycle ( I had 24h/7 before) . So I did switch to 12/12. After 3-4 days i noticed that something is happening in right directions , something very small is starting to form in the right place. But the smaller plants lower leaves started to show yellow, I did not worry and did supplement them with N rich supplements. Now after 10 days both of my plants has a lot of yellow leaves which also are sapless as when plant is over watered. I addition some upper leaves of bigger plant has started to turn brown over the edges. Needless to stay , buds stopped to develop. What suggestions do you have guys ? I really appreciate any help. In my first time i had similar problem, I ended up throwing the plants away. Thats why I am thinking it could be light problem.
