Three Leaves in some areas..

Hi,
I'm new to the website and have just been getting into growing a lot more. I started off with a clone from the local clinic of a Purple Kush. I have been wanting to grow for a while and decided to just take the step.

The problem: When I first go the plant, it was in kind of poor condition. Some powder mildew and some nutrient problems. I fixed those right away, but some leaves only had three leaves. At first it didn't concern me because they were so little. I figured the fifth ones would come when they grew out. Weeks later and they are nearly triple the size and still only have three while other have sprouted out with the normal five...The plant seems to be fine overall, but some of the "tripod leaves", as I like to call them still come along.

Is there anything specific that it could be ? The plants only about 5-6 weeks old. I don't know enough yet to even guess what it could be. I searched the forums pretty tediously and still haven't seen any threads about this.

This is my first post. Forgive me. I spend more time analyzing before I actually post something.

Feedback would be great ! Thanks

Just today i noticed a couple more little ones with three....Is there something wrong ? One of the bigger three leaf ones has little 4th n 5th ones now but just one.

nothing wrong, one of my plants has practically no 5 leaves and just all 3s, but i couldnt particularly explain why to you

Ok well that's better then hearing something is wrong. I've been looking at some people's pictures and I saw some where they come in really late because the leaves grow skinny and long.
But thank you. You made me worry less >.<
