Buds too airy/loose?

I'm starting my 3rd week of flower. I think my buds are looking loose and airy? What do you guys think?

They look just fine....and they've a load of time to fatten up. Don't worry...

employ good temps, air exchange/flow, rh, light supply and nutrient for a perfect finish

They're a little stretchy, I've seen worse. If you keep your temps in check you may not get those to form into huge colas, but you'll get dense nugs still. In week 3/4 the calyx have barely started to fill in, you'll have a lot better idea in 3 weeks ish if they're going to be airy or not. But really at this point you just have a lot of internodal space, shoudnt effect you too much overall. It'll be hard to keep the canopy and the taller tops both in a good temp/light range and that's about it.

Try either keeping it cooler or using some natural growth stimulants and hormones the next time around to form shorter denser plants.

Look fine.

Temperature will lead to foxtails. How hot is your environment?

Now that it's winter I've been able to keeps my temps at 72°. Had some heat problems early on but nothing in the past 4 weeks.
