Watermelon Auto from RoyalQueenSeeds

Day3: I think #1 stretched a bit, so i lowered my lights and added an oscillating Fan to harden the stems. He blows above them so they dont get the direkt breeze. Since they sprouted i just sprayed the top soil with water because first i was scared of them drying off even though the soils was kinda moist deep down and second i didnt want the humidity to go below 50% . I know these aren´t sweet spots, but i think the Autos with their Ruderalis in it are a bit more resistant. So far they look OK to me. #1 seems a bit yellowish to me, but i dont panic yet. Day7: #2 and #3 both bend over, the stem did a 180° to the ground, i try to support them now, but don´t know if they´ll make it... i guess i underwatered. Also I adjusted the Light distance and put it much more closer. Fortunately #1 looks healthy. edit: Mr.Pipi is 99% sure the big Fan killed #2 & #3
