Walking Veg. - Grapefruit Krush

So this is my first time growing under a Viparspectra 600w. I was recently using a 400w MH/HPS fixture. I wanted to see what kind of difference the light change makes. Got off to a bit of a slow start. The pre-mix coir substrate that I started the seedlings in was too dense and packed. Needed more perlite, so the seedlings got a little beat up looking, Once I transferred to the 3 gallon FFOF pot, she started looking a lot better. I'm only using the white and blue spectrum lights for veg. Once I switch to flowering I'll add the red spectrum. Of the 3 strains I'm growing, Abraham is, by far, the most vigorous.
