your final nutrients should be mid p and high k. no nitrogen or very little... autoflowers need more p than normal strains

looks like you have finally slowed my problem mate... Potassium defficiency is exectly what that looks like. I need to get some potassium asap. U think pot ash is best? Should I stop all other nutes and give high K? Would that be why my buds havnt filled out and pistils are still white?

i use guana and finish with a bit of tiger bloom,

I have heard great things of cha ching in this stage.
note im not fox farm exclusive.
