Okay so why are my leaves doing this lights to close maganese cal mag nitrogen so many they all look the same it only affects new growth starting at the top of the main cola fading to yellow green veins and curling upward not downard
Defoliation helped. aybe root bound or lockout by your description. Photos in bluepurple dont show real colours, do photo when light goes out and post again. Then maybe some ideas could arise.
Good Luck !
Organoman is right though cannbis plants are very close to tomatoe plants they are not the same plant they require different nuitrients. best of luck and welcome to grow diaries :)
