These little ones have not changed much this week but they look healthy, I hope they are gathering energy for the next weeks.
I will not add nutrients because the substrate should still support one or two more weeks.
the weather has been perfect lately, I hope it stays that way.
Keep an eye on the humidity they will respond poorly if it gets below 25% or so and prefer 60% in veg, they weather cold very well mine were in a green house with 48 deg F nights (8 c) common and it held up well. Went very very purple and MUST get enough light but thats all.
