Your diary indicates you're only giving your ladies some sort of root enhancer I guess... But you're now at a time when autoflowers start needing some other nutes.... so start them on some grow nutes but only about 1/4 strength of what is recommended. If they aren't adversely affected (probably won't be at their age), you can up the doseage to 1/2, etc. They're needing some nitrogen which will keep them nice and green ... and you'll also see them start really growing!
Good luck!
