Aero garden (MUFGA) Grape Walker Kush

There’s like 20 different bud sights. No strong smell at all just a little whiff when I take it out the tent but it disappeared in seconds. I replaced water and nutrients this week. I’ll hold out on that for the next 3 weeks I want to see some serious growth. I still don’t think this is gwk it must be something else. Idk what y’all think ???
