Leaves yellowing from the bottom up from the outer tips in

[Frogtownusa]

not sure what I did wrong. Successfully rooted them and they were fine for a couple weeks. Now all of a sudden the leaves are turning yellow, all the veins look very pronounced . Stems are turning purple . Signs of shock but I didn’t do anything other than give them properly PHed water. I don’t think it’s from overwatering. Any ideas would help. These are my only clones to work from :/

Thanks. Several of you have said that. I transplanted this morning and there’s some good amended soil. Will know in a couple days.

Roots were bald up in the bottom of the cup. I need to pay some attention to route training even at small stages
