Question on Water Leaves

My clones are a little past their 4th week, ranging from 5-8in tall. The majority of the water leaves are not extended like a normal leaf. They are all mostly 3 finger leaves right now but the 2 outer fingers are slightly tucked under the middle one. Almost like its in the middle of blooming like a rose or something and it hasn't completely streched out. Some are slightly twisted as well. I read that this could be a Magnesium deficiency, but I would have thought my soil still had enough nutes for how much the little girls could have used. I'm using a FoxFarms Ocean Forrest and a Local Wizard mix. I've watered only with water, superthrive and K-L-N root concentrate. I just watered last night as well. what do you suggest?

Can a Mod move this post to the plant problems section please.. sorry

That doesn't actually sound liek anything to worry about unless you are seeing scorching, spots, burns, whatever... clones behave oddly with some regularity, lol... give them time, and post pics as soon as your postcount allows you to/.
