Unusual Leaf Development

This is not my first grow (nor my last) however it is the first time I have encountered this. I have 3 strains growing and it appears to only be affecting one (white widow). Very strange curling in the small leaves that grow out of the colas. All the other fan leaves are perfectly normal. Is it strain related or maybe just a genetic thing with this plant. They were all cut clones, I never saw the mother. Also on this the main stem or stalk is very purple. Any help would be great.

I have seen that on my wht widow recently in veg. My was due to too much nitrogen( commonly called nitrogen claw) what NPK value are u feeding? They need very little nitrogen during flower

I like that...nitrogen claw...never heard that before

But i have heard another grower blame it on bad genetics before!lol!

They look a bit stretched or heat probs, pics of the whole plant might help. Peace

Thank you all for getting back to me, I am trying this round a SOG concept following LUCAS formula to a T. These had really no 18 hour cycle and went from clone, straight into flowering. It has been a few days since the post and they seem to be straightening out a bit. As for the stretching comment, could you give any advice for next time? I realize its a bit late this time around. However for the future it would be nice. These things really did shoot up during the first couple weeks even though I had my lights only about 8" away from tops. They shot up so fast I was raising the light every day almost. I even topped a couple to keep them all even. They have stopped growing in height but are filling in nicely. There are 6 ladies in there under a 600watt HPS in a basic ebb and flow in hydroton.

I cant advise cause i dont understand why they would do that, maybe some veg time before flowering to get them strong and healthy? Peace
