Leaves curling under/down

Hi all,

I am noticing that on one of my plants that the leaves are curling down on the ends. I recently transplanted into 3 gallon containers and put the plant under a 400W HPS light to start flowering. I measured the ph and it came out at aprox 5. Is this the reason? Could the light be too close to the plants?

Looking for ways to fix... is it even a big deal?
