I believe when you nuteburn the tips will turn yellow/brown and turn downward. I had this problem and thats how mine looked. That looks maybe like pests to me, but I'm not sure. See what other replies you get and good luck.

somemore info on this grow...

i had them under a 400 watt mh and the temps in the tent were about 82-86 degrees. i had them there for about 3 1/2 weeks. Then now i took out the mh and just put up 8 5500k cfls and got the temps down dramatically to 72-74 do you think that may be the problem? shocking the plants causing them to not intake the nutes as well?

hows ur ventilation any fans? do you foliar feed or spray them with anything?
i have similar spots but they appeared afetr i neemed one day so i was thinking its probly light burn from wet spots since it hasnt progressed.

Looks like K def/lockout and that you don't have enough ventilation, and possibly too much N.

You running your pH right for Hempys? I am not familiar with the style so can't tell you the target, but it's an inert medium and you should check the pH is correct.
