what does it mean when the leaves stary turning upwards??

its happening to one of the plants but only at the top set of leaves so far.
 
theyre 2 weeks into flowering....they could b needing water, they are getting water every 2 days, and its hot today, so more water may be the issue!!

they dont look like your pic...they are curling up at the tips of the leaves!!
 
usually with lack of water they will curl down, basically they try to shade themselves more so the leaves evaporate less... No idea what causes them to turn up though. I had something kinda similar, though closer to what purplehazin posted, mostly on the new growth at the top. I was able to vent the temps down by 5-6 degrees to around 80, went super anal on water ph (as well as adding mag/cal/iron), and started covering the soil with sand to prevent fungus gnats, and it cleared up. No idea which of these things had the most effect, I kinda think all those issues were causing me a lot of separate problems.
 
Phosphorus deficiency will cause leaves to burn on the outsides, yellow, and curl up. Since you are starting flowering now I could see that happening.
