Are My Babies Looking Okay??? Plz Help

My plants leaves are turning yellow!!! Plus my granddady plant hasnt budded that much, Looks very stemmy!!! The weather lately has been in the 70s and 50s low. I grow outdoors with Master nursery gardeners Gold organic soil and I water every other watering with Fox Farms Tiger Bloom and Big Bloom. I used a 20.20.20 orchard plant for for veg. My question is do these plants look like they have nute burn? And why does my grandday strain so stemmy with little pupils?? Ive had these plants for about 4 1/2 months. Only 4 of the six are grandady, The other 2 are Bubble berry Kush. Thanks for the help and hopefully I can have some good smoke by august. (The First 2 pics are of the Kush, The last ones are the granddady)

Thank god for reed fencing! Your kush looks fine i have several ouside that have a yellow leaf or two,no worries unless there are more than a few.I wouldnt use common soil if possible use royal gold coco mix or fox farms ocean forest,most my yellowing occoured from useing common soil.With the good soil you should be gravy.Good luck those look nice btw.HBR

Thanks HeadBangRocker!!! Yes, Thank god for those fences(LOL)
Hopefully I will get a nice yield from my 6 plants. The grand daddy looks a bit stemmy with no buds yet, But hopefully that will change soon.
