hi mate.. first of
all, interesting germination technique..il have to try it sometime.. :)
anyway autoflowers dont like transplanting that much, especially not moving it 3 times in 3 different pots.. plant in your final pot,mate. and use a bit loosened soil. and most important DONT WATER THAT MUCH ;) that’s why you got the lowers affected-plant cant breathe
peace and love and good luck mate
