3x Mephisto Forgotten Cookies 2x4 tent

First time trying to grow cannabis, just finished putting together my setup! Going to be running a 2x4x5 tent with 3 HLG QB 96's driven by a HLG 480h-54a. Planted 3 Mephisto Forgotten Cookies right into coco perlite and worm castings (2x3gal, 1x5gal) at 00:00 on Sept. 20 and watered tent was held stable at 80f and humidity domes were used. By the Morning of the 21st one 3 gal and the 5 gal had sprouted. The other 3 gal popped later that evening. Third seed to pop has some interesting features, and appears to be growing 3 first true leaves.
