Black Widow leaves problem

wrinkly, severely fucked up ugly leaves all over? or are lights playing a trick? If so, a disease or genetic defect. they never do well.. some may produce a quality bud with shit yield but rarely worth the effort or space in my opinion. Grow lights can make some stuff look much more severe than it is. I can't stress enough to be sure it is actually "fucked up all over and wrinkly / spotty etc" (unnaturally so and doesn't fit a leaf symptom chart example at all) before trashing it or powering through .. if it's just going to be empty space, go ahead and keep it alive and see the result. This familiarity is needed to feel confident that throwing it out is best in future, and to pop extra seeds to mitigate these sorts of risks.
