Two of the five have shown to be mutants. The mutation is quite hard and causes the leaves to grow crippled and with an uneaven color. I keep them for the moment but I don't think they will become anything viable (I've become a refund from Fastbuds; shoutout to them).
I turned the light up to 50 as the first set of leaves really came out, then up to 70 as the second set appeared. I think I should've turned it quicker up, since the stem seams quite long in comparison with other diaries I've seen. I also started lowering the light gradually, about 2 cm a day.
Two of them started having twisted leaves, which is a sign of an early calcium deficiency, so I started increasing the dose of cal-mag agent in the solution and foliar feed them with a calmag-wet betty solution at about 0.8 EC.
The leaves seem quite light green, maybe a nitrogen deficiency ?
