Ugly mutant lady: Red Kush Auto

DAY 1 The little lady has just sprouted after two days under the soil as a pregerminated seed. No helmet on the seed, which is a good sign and less bother. I spray the soil around the plant with water PHed to 6.2 three to four times a day. The plant is currently about 70cm below the lights since it's the first time I use these lights and they're pretty powerful LEDs. Will see how the seedling reacts and may move it up or down accordinly later on. Yellow sticky traps have been placed because my outdoors plants have gnats and there are some gnats inside too. I'm also watering with BTI (bacillus thuringiensis) so as to prevent gnats larvae from damaging the seedling roots. DAY 2 The girl stretched out a bit so I moved her closer to the light, now she's 47cm below the lights instead of 75. Let's see how she takes it make changes accordingly if necessary. DAY 3 Watered with 250 ml of water PHed to 6.2 with addition of BTI. The plant keeps stretching quite a lot, and is now 6.5 cm high, but the stalk is pretty strong and it doesn't need any support even with a fan slightly blowing at it. I placed a small fan that I turn on for an hour or so a couple of times a day so that the stalk gets stronger. So far that's not the most beautiful seedling I ever had, but I think that's because it's too young. Let's see, time will show. DAY 5 She's growing alright, although she stretched quite a bit more. But it looks like it slowed down and is now growing wide as you can already see the second set of leaves forming. I propped it up with more soil today. Will probably water it tomorrow. DAY 6 Watered with 500 ml of water PHed to 6.4 with light addition of rooting nutes. The plant is growing well. DAY 7 The second set of leaves is forming well and you can already see the third set of leaves starting to form, too. The leaves are deformed though, but it looks like it doesn't mind it. What can it be? A PH issue?
