Mothers Durban Poison, Cafe Racer, Wedding Cake, & Pineapple Express

Mothers Durban Poison (DP), Café Racer (CR), Wedding Cake (WC) & Pinapple Express (PE): 2 weeks from Germination and they are green and healthy. Surprised at the growth of CR. At first, I thought it was stretching but the stem was strong and thick and fully supported itself. Took dome off because it outgrew it. It didn't seem to like that looking a bit dry and curled leaf. Made a larger dome and see if she perks up. Disappointed at the growth rate of WC. Doesn't seem to want to grow much. As a Indica Dominate I expected it to be short but not this short. Increased lighting to 550ppfd to try to spur some growth. DP has been growing well no problems. Temps have been consistent at 73F-78F, Humidity 80% Domed/56% undomed, CO2 500ppm-650ppm Night cycles, 800ppm-1000ppm Day cycles, watering according to medium dryness consisting of a direct quick spritz followed by soil surface wetting of about 75ml-150ml twice a day. Sometimes when Medium looks saturated I will not water. Watching for Root development to transplant into 1 Gal Pots. Probably a week or 2 from that. I've been switching from Domed during the day and no Dome during the night to acclimate them to Veg Environment and combat any potential mold/mildew.
