Autos need alota light ,long periods of light sum hav ther lights on24 hrs straight , your plant will start flowering too soon if its only getting 12hrs of light per day
Alota sticks in your soil no good for babies u wanna get rid of large debris 4 1,, next time u transplant. Your humidity is too low and your day night temp difference is too high u wanna keep 5c difference or lower
Wait a bit see what others have to say..but if hes spraying the plant like that it means its been infested probally ...why risk infecting your whole tent and other plants 4 1 clone
I'd chuck it out the window pot soil an all ,thats the most miildew i've ever seen omg,never take clones no matter what yur buddy says, he jus pawned his garbage off too you ,
