Just my observation looks like you have some heat stress. They are curling up and ripply because they are trying to dissipate heat more effectively...What are your canopy temps?

And be sure to fill out the sick plant guide in the sticky in this forum so the experts can help you.

Try to get non hps pictures and it would be easier for someone to help you some of your tips look like spindly ph issue, but I can't tell real well from your picture. Do these 2 things and someone can help you for sure. I feel I am spot on on heat stress though...

Had a similar problem, turned out to be heat stress, your temps look OK though.

Is temp constant at 24 ?, I took the plant away from heat for 3 days and it was fine, only a newbie myself, plenty of good folks here that will have a better idea.

Good luck

Every thing I have read looks toward heat stress or light stress..I have a friend says to much nutrient but in that case I only gave .5 dose

if it was heat stress could this of happened 10 days ago and now i am seeing the results of that

What size are the plants and pots? The leaves look fairly large and soft to me. Usually, if the lights are too bright, they'll be smaller and kind of harder, or leatherier.
