Quick Feeding Question.

I have a quick question.. I transplanted my clone into a pot from a peat pellet about a week ago (Roots were poking out of the pellet good) and it has noticeably grown in the pot so the roots have settled in a started spreading/growing. I was wondering when can i start giving it some nutrients? im just going to start with foxfarm grow big and big bloom. Im assuming pretty soon if not now, but wanting to make sure.

Thanks

give it a week to settle in a little more. As soon as any of the growth loses the deep green color for a hint of yellow you can start feeding.

it definitely has gone from a dark green to a lighter green, that i did notice.

I still don't feel as if I got a good answer. It's been 10 days since transplant, I can definitely tell it's lightened in color to a light green and it has grown atleast 2 new sets of leaves. Do you think I could start feeding big bloom and grow big? I'd probably start at half dose unless u think otherwise.

heres some pics if they help. is it ok to give it some big bloom and grow big?

this is the day of transplant

these are today...
