Fastbuds gorilla glue auto

Hi amigo ! 1st I think you could fix your PH at 6.5 , it's the average in soil . 2nd You've directly switch from your growth nutrients to your bloom nutrients but it is better to mix them both during one or 2 weeks of transition like 50%/50% the 1st week then 25%/75% to end by the normal ratio , it provide enough Nitrogen for the end of the flowering stage. 3rd You should add some Cal mag , it is often good to add even a little amount to prevent any def as plants needs a lot of calcium to achieve their buds fattening. 4th Your plant is an Auto so you don't need to worry , she will her flowering before yellowing !! I hope it will help you a bit 😘
