Where did you get the genetics? The 3-fingered leaves is concerning. What grow light are you using? Also, what is the pH and PPM of the soil runoff? Additional info is needed in order to properly diagnose.
@Nelson Witcher What made you think heat stress if the temperature is 73F? Do you actually mean light stress?
The pH going in isn't what the pH in the medium is. If you can get a soil runoff pH and PPM reading then I can advise further. Without those numbers we are guessing on what the problem could be.
