Depends on what you are growing in. Need more info for people to help.
I run a 70 soil, 10 perlite, 10 coco, and 10 earthworm castings. I give a light feed at the start of week 2. If you are using a fertilized soil like a potting mix, then you wouldn't need or want to add anything yet.
The more info you provide the better the answers you will receive on here. Such as soil, what types of fertilizer you plan to use. Watering habits.
Best of luck on your grow. Looks good so far to me.
