Started my first grow and things were going almost perfect. Until yesterday the leaves started curling up and now there all brown spots and holes all over. And not just on one plant but on all nine of them. I've researched and think it could be heat stress or maybe over watering but I'm unsure. Need help identifying exactly what it's wrong. We had a hot humid day and then the last two nights temp has dipped to 50. It's hard to tell in the picture but there are several holes and every leave is curled up. On new growth as well.

In your 1st pic you can see then sun shadow on the plant,the other leaves are trying to turn towards the light/sun
Look nice and happy to me! Little holes are just some insect eating on the leaves. Spray some Captain Jacks or Neem on her and you'll be good. Sent from my LM-X420 using Grasscity Forum mobile app
Looks like leafhopper damage....always a very distinct spot from where they pierce and suck juice. Yellow sticky traps will get a good amount of pests that want to feed on your plant...I recommend highly.
