Thats ok I'm no ace grower either , a bud enhancer is just one of the many different additives to add during the flowering stage . Some work great others just a waste of money , I just ordered some big bud from advanced nutrients and am asking around as to who uses what . Remember it's always better to underfeed than to over feed . Easier to add more than to watch you plant burn ! I jewelers lupe works good , if you've got good eyes you should be able to tell cloudy from clear etc. The hairs should be about 80% red or brown and the buds should look nice and swollen and heavy !!
