That yield is fucked for a 40 day veg. you need some bat shit in your flowering stage. specificaly fruit bat shit, flying foxes if you can get it. its about 50 bucks a bag for 10 key. its well worth it. gaia green is a bc company, theirs is good, so is there power bloom(i use both, 100% organic) and they will bump up your yeild. Try toping it with a scalpel(those top cuttings make kiler clones) and if you are useing soil, which i recomend, make sure not to over water em. if you are really careful tho, breed that bb from jordan to the kaia. after about f4 you should have some killer shit. a warning tho, dont get into heavy inbreeding and back crossing. look up charles II of spain. when its close familial genes. it fucks up everything, animals people plants. the only tie inbreeding is acceptable is when its landrace plants, trying to keep em pure but stay away from that, backcrossing fucks shit up. Im on my frist breed now, but ive been given solid advice, thanks to history
