First off, it's better if you don't disappear for a month
. Second, how many days are those two? Third, neither look to me like they've gotten enough light. Fourth, what have you been feeding them, in what amounts, and how often?
We'll need more than those pics to get you back on track, but all is not lost yet. The Kush hasn't even flowered yet and the OG has many weeks left to work on getting those buds to swell.
Here is the FF feeding chart for photos, but it works for autos if you start low and work your way up to their numbers over a few waterings:
I'm in flower, and besides cal/mag+, I'm using Open Sesame at ½ teaspoon/gallon, Tiger Bloom at 2¼ teaspoons/gallon, and Big Bloom at 4 tablespoons/gallon. In veg I was just using 2 teaspoons Grow Big and 4 tablespoons BigBloom but my soil isn't as hot as FFOF. pH to around 6.5.
Give us some more info and we can give it a shot!
