Hi. Hard to say, where is problem exactly, with unknown pH, EC, soil composition etc... But I would bet on nutrients/pH imbalance. Excess of any nutrient can block some others. You fertilized it with P+K only once but still, this amount without enough light and temp. can cause anything, especially with this unstable conditions.
Healty plant in week 5 looks 4x bigger than yours (10+ internodes). I have tried indoor jack auto (some others too) for first time in 15L fabric pot under 19watt bulb (from week 3 under 4x19w bulbs), and its really not comparable. From week 3 it was really crazy (started LST after week 2, because plant already had 6 pairs of leaves and was 15cm high) and each week it grows exponentially faster and faster. Every week defoliated 2-4 fan leaves big as hand.
What I want say... Fast growing healty plant is not so vulnerable towards any small mistake or small amount of pests. And about nutrients feeding: "less can be more"
Good luck, I am looking forward to this/next week ;)
