hey man, she's not fully showing sex yet but she's looking like a lady as it is, but maybe that's wishful thinking on my part ! basically she's not slow she's a plant that's just not getting enough light. There are only two nutrients on this earth : sun and water, in soil your plant only needs light and water, but basically the light is a tiny bit weak so she's lacking the energy to really bust out ! she"s already showing pre flowers so she will start to flower next week for sure. You can do the math 9 weeks reccomended 4 weeks veg, 6 weeks actual veg so 7-8 weeks flowering before the end 6+8 14 weeks total expected with that light. You want bigger and quicker buds then get a bigger light. You're gonna have to be patient bro, make sure you maintain that lamp to plant distance, she ll be stretching the next 3 to 4 weeks, you'll want to be checking up on her daily! hope this helps ! 🚀
