Pics are real blurry, hard to tell, but its definitely a water issue. How close are those lights? Back them off a little, also they look thirsty, but how often do you water/ how much?
hey doobie ur baby looks like it is having an issue with the amount of water that they are recieving,let them dry out for a while and things should sort themselves out....may i also say that your stems are looking a little red/purple-this is usually a sign of stress....but no worries it should work out for you in the end my friend..
good luck mate.
