Take a look at these need help please !

Okay so its my first grow and i am using MC soil ( never again ) and I am running 12/12 for about two half weeks. I am also using fox farms grow big, I am applying the light application one every other watering. At first my bottom leaves where turning yellow, and a few fell off, know all the upper fan leaves are starting to turn, the small leaves are fine, but for some reason all the fan leaves are turning on me, any ideas here thanks for the help !

looks a little nitrogen deficient, but because you are in flower it isn't such a bad thing. are you giving any flowering nutrients (tiger bloom?) or still using the grow big? Do you give supplemental feedings of Big Bloom as well?

well i was only using big bloom, once every other watering, however i do have tiger bloom but have not used it, should i maybe apply tiger bloom once a week ?

yep. grow big is for vegitative cycle. your well in flowering stage, so tiger bloom is what ya need.... you can try a routine of water, water, nute, water, water, nute, or give nutes every other feeding, whatever your plant can handle. good luck
