I just transplanted my babies that were looking great from solo cups to larger containers on June 19th and all of a sudden the leaves are showing burn on tips and edges. This is twice that this happened to me this year and I had to trash my previous grow. I have been growing for a few years and have never run into this problem before. Same set up as previous years, I am neurotic about humidity and temperature, light strength and height are fine (viparspectra v450 led), and always PH my water. If I had hair I would be pulling it out. I really don't want this to go too far and have to trash this grow as well. Any suggestions would be helpful. Thanks!
