found this deficiency about a week ago, still haven't managed to solve the issue, just a small 1x1 600w

using an Australian brand called Nutrified coco a&b, Nutrified bud burst, Nutrified pk heavy (very much like pk 13)

currently 4 flowering in pb8 planter bags currently in week 4. this deficiency has been showing about a week and has only gotten worse.

feed young plants at 400ppm 500ppm in veg

bump up to 600 - 650 in flower, which is the same base a&b but adding a few other things like kelp based bud booster and pk heavy. have tried higher and lower numbers but that does not seem solve anything.

water every day if I think they need it or not, usually aim for 15% run off.

tried different ph ranges but always seem to have this same deficiency show up around the same time.

first signs of deficiencies are showing from the very top and new growth, it seems to be to tops that slow down the most in growth. I'm thinking potassium deficiency but he can never seem to correct this. even calcium deficiency enters my mind but never get any gold or brown spots.

as the Deficiency progresses the small bud leaves start twisting and curling over sideways

this issue always pops up around weeks 3 and only gets worse, seriously affecting harvest.

added some examples from the last lot showing leaf twisting
