FASTBUDS PURPLE LEMONADE X2

over watered. over fertilized? dial back and see what happens. wait for top layer to dry before watering.

I disagree. Leaves are ribbed from being water logged forcing them to curl down in that fashion. They are definitely overwatered and starting to get deficient. Plants look small for the size of pots, so don’t water to runoff unless roots are well established in there. I suggest you let them completely dry out as quick as you can, and only then resume watering and feeding both at half the rate previously administered and back off your lights. You should aim for a 3 day wet/dry cycle. If it takes longer than this, it’s too much water. Trust me! Been there! Cheers 🍻

Seems like they're really under watered, you have 10 liter pots, should be watering with at least 1 liter and seeing some runoff at the bottom. With this temperatures, you might need to water them twice a day, once when you start the lights, and then once at the afternoons/evenings, you will notice the soil gets really dirty even after watering the same day in the morning. When I had the 600w sodium before switching to leds, on summer I had days with 34-37 C, and needed to water three times a day! You will see, they are droopy, you water them, in 5-15 minutes they will be amazing. Learn to detect the droopiness and keep them watered and happy!
