She should start picking up the pace, been letting her dry out completely between waterings
Lowering ph down To 6.0 to see what happens
Top growth looks like it is showing ph problems at the roots.
Nothing but water and only two Solo cups per watering untill dry
Next going up to 3 Solo cups per watering
Nice looking plant .... I just got done harvesting a Northern Lights Auto and a AK-49 Auto myself, now awaiting harvest for my White Widow Auto, check them out if you can, I wish you success with rest of your grow and ...... HAPPY GROWING !!!!
