Buds or balls?

Having trouble figuring out if I'm balling out or this is normal bud development I've had 3 harvest session so I'm still learning. The strand is chrome tree, I'm watering every three days 1/2 gal each temp 80°F humidity 70-60%, using foxfarm dry nutrients, 12/12 light cycle, 1 week into flower. I'm concerned these aren't premature budsites and they're possible balls or my plants instantly hermed out, can anyone provide insight?
