Now %33 warm white in the area. I changed all the tubes for 2700k and taped folio like here: Can I use foil on my florescents?. They look shiny now

Changed water to only deionized water with 0.7 dosage of Root Complex and normal dosage of Supervit.
For once added PowerZyme and watered 20 to 30 ml per plant. I'll use this PowerZyme weekly.

1st gen developing well enough. Their second set of leafs are already with 5 corners. Tiny side stems are more visible.
2nd gen is developing very healty.
3rd gen just too young yet.
