Curling up , pics.....

SO I HAVE 10 PLANTS THAT WERE UNDER 400W HPS. TODAY I CHANGED IT TO MH 400W. BUT I AM NOT SURE WHY MY PLANTS ARE CURLING UP. MY PH LEVEL WAS A BIT LOW AND I AM TRYING TO RAISE IT SLOWLY BY SLOWLY WITH LIME. DOES THIS LOOK LIKE PH OR SOMETHING ELSE ?
I AM USING MG MOIST CONTROL WATERING MY PLANTS WHEN MOIST METER IS LOW, TWO 400W MH ON ALL PLANTS AND JUST STARTED FEEDING THEM FF BIG BLOOM HALF TABLE SPOON WHICH HAS BEEN A WEEK FROM TRANSPLANTING. WHY ARE THEY CURLING UP. THANKS ....

Back off a foot and watch for a day and if better lower a bit over a few days like 3 or so inches at a time

Also, make sure that you don't have a strong fan blowing on them directly. The most likely cause is Transpiration which is caused by too much heat or too much dry wind. Move the light and make sure there's not too much air blowing directly on them.
