Leaves dry and curling under???

The closer the Better is the old Rule for Hps in Flower..... does your fan blow on that particular plant with the weird Leafes??? I had it several times that the Airflow caused that on Youngsters over here. Also ph runoff of 5 isnt that good as the others already mentioned. If u need a quick and easy solution try Baking Soda with the Feedings it should up the Ph.

The fan was positioned higher than the plants but it was blowing towards that 1 plant. I changed the fan to the other side so it's now blowing left to right
