Is there anything i can do to get the buds to fill in and get a bit fatter?
they are quite thin at the moment, i'm feeding;
ionic soil bloom
cal mag
pk boost
guanokalong
Should I be giving her anything else?
Hey 715Creeks!
She look better then well. Don't overfeed this girl! all you can do is to grow her out. I don't know what "true watt" you use but for the size listed, you don't need to worry my friend ;). One thing the lemon likes, is to dry out the pot a little bit then give her the feed (pref week 5 in flower). Thumbs up and Cheers!
