I watered with the first 4 bottle of nectar and slf 100 then the same but with pk 13 14 then I waterd with ph 6.40 water with slf100 .they are all just swelling up right now.i will probably just use ph water with slf from here on out.i might do one or 2 more heavy feedings though.im thinking they have around 10 days left some probably closer to 15 or 20.
