Yellow Leaves, Only One In Crop :(

Using Foxfarm OF and following there nut schedule. PH is 7 on the nose. Temps are between 72-84 with 40% humidity. 1 week into flowering and this started showing up on one of the girls. Only one of the group, what do you think rollitup.org? I don't have a clue...

mag def shuld be in smaller leaves

Hold on there DOGGIE!!! Lets look at the pictures. He has one plant on the table, and one other one next to it. then another plant over to the right and DOWN on the floor. They are just kind of placed where ever. This tells me that they are getting what ever light they get. They are just placed where ever, at different elevations. But the most important thing is that the soil is bone DRY, and there is nothing under the pots to catch the run off. This makes me think they are just getting a little water more often so not to get the floor wet.
All of this makes me think that the other needed elements, like nutrients and such are being neglected also.

looks like you might not be getting enough light to the lower part of the plant...or maybe a K def

To the soil and food question, I am using fox farms ocean forest soil with their recommended nutes (tiger, big bloom, and grow big). Following there feeding schedule as well...

That picture was taken while I was watering them. They have a good home in a good tent with a 400 HP's and she has 7 other friends with her. They are not being grown where that pic was taken...

Hahahaha. Ok. I better understand now.

I still think that when you water them, you are not giveing them enough water to have run off. That soil is Bone dry. I would also drop the PH a little lower.

to much Nitrogen has caused this...dark grren leaves, and margin curl...be careful...my plants did the same thing...just flush, and water one more time after the pot dries out...then feed as usual...FF nute schedule says something like 1 tsp. per gallon every other waatering...no...thats way to much brah...i grow the same, just no more 3 gal. buckets.

your PH using FFOF is fine...maybe a different type of soil i would drop it...but FFOF has plenty of what little boron and manganese in it that the plant uses...i keep a higher PH as well...normally 6.8, but sometimes in a rush it ends up being 7...and mine are healthy as can be.

Makes sense, I'll try cutting the N dose in half...i did a light flush, I'll do another one on the next watering.

thanks everyone...
