Hey guys

this is my first grow. Wss skunk faminized/photoperiod. I've kept her 7.5 weeks in veg and since 4.5 weeks in flowering. All together 12weeks.
She is under 300 watts Led light, since 5th week of her life i have been feeding her with basic nutrients. Micro/grow/bloom. Since 3 weeks i stopped adding nutrients and just by every 4th.watering adding bloom nutrient mix with water.
I think that maybe already in 4.5 week of flowering it should be more on her. Size of buds. But maybe I'm just not being patient. I have read somewhere that it can take a little longer for some plants to start putting up the bud weight.
What do you guys think. Is it maybe slower strain?
