claw leaf and weak leaf prob

High! I am have a couple of ladies about a month old and they re looking great except for two leafs, but since I want to know more I am asking anyway, what can cause this problems.
The picture of the claw leaf is very clear, the other one is the same plant from other angle, the leaf I am talking about is the big one in the middle.
Sry if I am being paranoic, I just want to learn THX !

overall they look ok, some tilting of the leaves is normal. how often do you water? whats the pH like? and the temp? and what lights do you use?

I'm gonna refrain from answering this because I have the same prob.

av just eperienced the same thing but mine came straight after i flushed them! the net day they had claw somethink rotton but a few days later and its as good as gone, but after doin a shit load of research on the claw affect i got a flurrey of different answers, like to much nitrogen/ over water/ ph inballance/ and maybe one or 2 other reasons also, so just choose which one u think it may be and research it see if it coincides with what u think, like a sed i over waterd mine coz i did a flush so that makes sense y it apened to me! but most forums were saying it was N toxicity ( to much nitrogen ) or over water as the 2 main culprits!!! good look guys,
by the way ur plants look real nice other than that n as regrds claw u av it very little as some will b right back on them selves but urs r not bad atall. peace!

That is not a true to form case of "the claw."

Due to lighting conditions pictures are often not truly representative of plant colors, so I am not sure about what I thought I saw. In the second picture the leaf in question looks like it has something of a dullish blue-green coloration. Is that how the leaf actually looks or does it only look that way due to lighting conditions when the picture was taken?

If the color is a dullish blue-green then you are giving your plants to much nitrogen. That can lead to "the claw" due to excessive levels of nitrogen in your growing medium causing nitrogen toxicity which destroys the plant's vascular system and increases transpiration.

i agree with Brick top, you mite be giving your plants too much N, when i experienced this "claw affect" it was when i was foliar feedin with too much N, i later cut back on all nutes and gave my plant a deficency but thats another story,
like brick said if they look dark/dull green pluss this claw, too much N what do you think? what nutes etc have you been giveing your plants?
