Calix too big, is this right???!

That's a common ruderalis mutation... Hope this helps

The light is not strong enough to fatten up those buds. The light is the main dish for cannabis. So if you use a stronger light you will grow fatter plants. And just to take your doubts away, this is not a hermie and you will still get some nice weed to smoke from your plants. But if you want big fat buds you need to use more light. At least 200-300 watts per square meter. 400-600 is giving the best results. Enjoy the harvest buddy! 😋

looks like foxtailing.. you've got a 50w light covering how much space? might need a bit more to form more solid nugs. gentics can be a cause too. go google search 'dr. grinspoon' and see an extreme case of stem elongation in flower, lol.

They're weird looking colas. But beyond that. It's nothing you did or can do, well at this stage. Below the tops will continue to bulk up. The tops. Well, you could lightly trim the top larfy bits, "but not necessarily needed at this stage. She's already wasted energy making them" up to you though. Nothing you really can do but push n and bulk her up. Green sen and the pk booster you're giving will help in that department. Sativa dom buds can look like that. As can indicas. So, its just a pheno form. Nothing more, and certainly not a hernie so you're all good. Good Growing
