Lighting

Guys I raised the lights all the way up about 4ft from the canopy and they are thriving

Add humidity. My GSC's edges are curled because I keep letting my humidifier run out of water. The relative humidity gets too low (for the current temperature and nutrient concentration) causing the plants to transpire too quickly for their size. Try targeting a VPD less than 1.

I had similar issues with my new light, I'm hanging higher than mars hydro recommend and still only running at 70-80%. It's just about finding the sweet spot and the correct ppfd/lux. There is an app for your phone called ppfd meter, I don't know how accurate it is but it does give you a rough idea of how much light your plants are receiving, give it a go. 👍🌱💡

They are wilting because the light is too strong. Raising it should help but full power may be too much at this stage. Maybe try full power in a couple weeks when the roots are more developed.
