Nitrogen deficiency in clone transplanted 9 days ago?

It could also be due to over watering and/or heat stress, as well. Or, even a little bit of shock from being transplanted. If you just transplanted it into fresh soil, I doubt it's nitrogen deficiency. Check your water with a pH strip and see if it's between 6.0-6.7. If so, it isn't pH. Check soil with your finger to see how moist it is. Or, pick some up and squeeze it. If you can get moisture out of it, that's the problem. Let the soil dry out before watering it again and you'll be good to go. I hope this helps.
