When you X-planted it, did you "water it in" heavily to the new container? It could just be a symptom of that. In that case, just wait a long time before watering/feeding. An additional fan might help "dry it out" too

The yellowing is not necessarily a nute deficiency, could be a light issue (not enough) - Although if it hasn't been fed yet, a little N can go a long way. Perhaps foliar feeding it a high N fert so you don't have to water it down anymore? How much light and how far away from the plant is it?
