Mandarin Cookies R3

Dmars 9/20 2 seeds put in paper towel. Number 1 will be a 33% coco, 33% peat, 33% perlite mixture with all my normal additives. Number 2 will be a coco and perlite mix with the same additives, no peat. The additives are pelletized gypsum at ½ tsp per gallon and wollastonite at ½ tsp per gallon. 9/21 Both seeds have popped so I flushed both pots with seedling water until runoff EC matched input EC and put them in. Lights are set to 180 PPFD for now.
