It says in your diary that you just transplanted 2 days ago, give the plant time to establish in the new pot. It will take a few days before it starts taking off again.
You just transplanted and the soil you're using should have enough nutrients in it for a few weeks.
Your pots look rather dry, make sure to saturate your pots fully. Underwatering will make the plant show deficiencies.
The plant can't absorb the nutrients in the soil properly if there's not enough water.
