Hi all! Something interesting happening here! As you can see, despite the fact that they have the exact same life, #2 is showing what I identify as heat stress or bad VPD signs. At this point I do believe it's a genetic trait, I mean there is really nothing that went differently for her compared to her sis! If you have any id of what could be the cause of this difference I would like to ear you please. I thought about the fact that she is placed in the middle of the two lights so maybe in a hot spot but really those are two 100W lamps and they are far above the plants so I don't think it's the cause. I even didn't measure the PAR but I should probably do it just to be sure. Anyway they look healthy and are growing well at a very similar pace. If the two are females I'll definitively keep #1 . Cya!
