I’ve grown a long time, although most it was outdoors yrs ago……but IMO autos are more challenging. You obviously got the veg stage perfect or your plant wouldn’t be as large. With autos I didn’t like the fact that any bump in the road during those first 3 weeks could derail your entire grow. So I gave up autos, although I may try another at some point.
Anyway, I would keep feeding and let her go for another week or 2…..preferably 2. Don’t fret over the yellow fan leaves. You don’t smoke them and they have to come off anyway.
I would remove any leaves that are dead or really close. You don’t want them dying back into the body of the buds. Snip em and toss.
Otherwise, you’re solid for a nice harvest.
One last thing…..I wouldn’t wait and wait for more amber trichomes. It’s been my experience along with many others that some autos (and some photos as well) simply don’t go amber easily. You risk losing the terps that make this weed so enjoyable.
Good luck with your health……and I hope this mj provides you with some good medicine.
