Seeds popped but stopped

[SoberGrower]

So this was supposed to be my 4th run. So far I've ran 5 mephisto dbl grape x strawberry nuggets, then 4 fastbuds purple lemonade, then 6 fastbuds banana purple punch. This time around I've changed a few things but up until this point I've never had an issue getting a plant going. The only change in how I do things really that would play any role here would be the new floraflex 700w lights causing an increase in temps. So previously I'd pop seeds by tossing them in a shot glass full of Poland spring water for a day then into paper towel and a zip lock bag not zipped all the way closed for a day. By this time I've had nothing but 1/2 tails that turned into plants. This time around i popped 4 speedrun terp sneeze which ended with one dead seed that wouldnt sink or anything. Popped another and it went well and they went into the 4 pot autopot system I picked up. Then I tried popping the remaining 8 terp sneeze I had. 7 of 8 popped in the shot glass but made no change in the paper towel. I didn't know what to do and planted them in hopes they were just running slow and would eventually sprouts and grow. 2 days later and nothing. Since then I threw 3 mephisto Amethyst nuggets in the shot glass for a day, they popped then went into the paper towel, and no change. The only real change I believe is the temps in the tent because of the lights but I thought warmer climates were better for seeds. Any help would be greatly appreciated. I'm afraid I killed at least 10 of these 16

The heat shouldn't bother them I only soak them for 3-5 hrs then direct plant I usually see them above ground sprouted in 3-5 days. I wasn't a fan of paper towel method and that has nothing to do with the microscopic root hairs being damaged but being able to keep the moisture level proper I was lucky if I was getting 50% germination with that method I get near 100% germ rate now
