hears what Seymour says about PK mate
!...Im guessing your running it now though ?... still good info
Q...

SB's lazy grow lookin better than most who ppl who are ocd in the garden. Looking very good as usual Seymour. Im paying very very close attention to your pk regime; so you started the pk regime around the late 40's day mark (I'm assuming) was the first week of canna pk13/14 at 2ml per L with a new shot of pk every other day? Than followed by hammerhead at 1ml per L and topped up with plain water from here on in until flush? Sorry for so many questions SB, just want to make sure I'm following along correctly and maybe one day I could get close to your level. Thanks.

i tend not to worry to much about which week i judge pk time on the formation of the flowers, different people will tell you different things on when to to use pk boost but i personaly wait until the flowers are formed
you get pre flower stretch followed by flower formation when the pistils are curling up the stems to form buds when the buds are pretty much formed the next stage is weight gain and this is when i hit them (some growers like to do it in flower formation stage) my strategy is when the flowers are formed they gain weight/exspansion so i wanna encourage growth as much as possible. also having the right ph etc plays a big factor (5.8-6.0 for dwc) but by this stage of the grow you should be fully in control
i use pk 13/14 @ 1ml per ltr so a 15ltr res would have 15ml of pk then every other day ill top up with water and another 15ml of pk booster and then ph adjust, also i run higher ec on pk week, if the plants are on 2.2 ec on pk week ill increase it to 2.4 and the following week drop it to 1.8
hammerhead is just a lower ratio pk booster of 4/9 so sometimes i like to follow on the next week with this just to keep the fruits expanding. again i use that at 1ml per ltr, if you use it at 2ml per ltr you buds will foxtail due to higher concentraion potassium and i like my fruits to be consistent
an alternative to pk 13/14 is hammerhead at 2ml per ltr which gives you a ratio of 8/18 or you could also use superior potash by canadian xpress which is a 9/18 pk boost again its just down to choice of the grower
hope this helps "
