Advice on Organic PK 13/14 booster alternatives?

Im currently 5 weeks into flowering with my first grow. I am currently growing White Widow in biobizz all mix supplemented with Bio Grow + Bloom ( with a touch of molasses)

I just wondered if there was any product to help with boosting my harvest potential like the aforementioned in title? I hear both PK 13/14 and PK 9/18 ( hammerhead) are products ive seen lots of peeps rave on about and claim that it really boosts bud size etc etc.

I cant see anything in their info to say that they are organic so im assuming they are not. As i've started off organic im rather hoping to stay that way, so any advice to alternatives guys?

Heres a few pics of my plants so far taken from my journal

ok 13 peeps read, no advice? Is there any booster that is organic that acts in a similar way?

 

I don't know of any organic boosters.
But, those girls will swell up before they are ready.
Good luck.

 

Thanks for your reply, heres hoping

 

BAt guano. I prefer indonesian. Top dress it a tbsp a gallon or a tbsp per foot of container. In a five gallon I will sprinkle a few tbsp her and there. It can burn so not too much. Water it in then with your reg feed. Look for the P of 12 or so. Sunleaves has it cheap on eBay. Nice shit. lol.
