nuit help

Can someone please help me, I know turned down tips as a sign of nitrogen toxicity also why are my buds so small?

ok well my little girl is 1 week into flowering and is showing signs that it need food as far as I've been told I bought cal mag and the fox farm trio pack ( tiger bloom grow big and big bloom ) my question is how do i use it all I have used is a promix soil no nuits but another one of my issues...

Does anyone have a nuit schedule for fox farm for an autoflower grow?
