I ran into some problems. My cannabis seedlings are 3 weeks old, but they are very thin and unable to stand. There are not too many leaves. Some of the top leaves have yellowed and the new ones have grown below Leaves withered and died. I would like to ask how this problem can be solved. And im in china no one can answer this questions for me . many thx for all the cannabis farmers. its my first grow ,all autoflowering. many thanks bro。
All my plants have encountered the same problem, is it because I did not change the ph
