seems like overfeeding, it can happen with GH nutes. is the 3 pieces one? (bloom micro and grow)

In your previous post you said something about 330 ppm, and you're in flower.... I feed freshly rooted clones at about 300 ppm, I feed flowering plants at peak flower around 900-1100 ppm... I suppose if you are using some sort of wonder nutrient maybe ~300 ppm is enough. If you are using tap water 50-100 ppm is already there so you only really have ~200 ppm of nutrient which is insanely low imo...

more potassium is needed

probably phosphorus and cal/mag and a world of other nutes too

but potassium sulphate seems to make the biggest difference past week 2/4 of flowering

I gotta stick with your nutrient level... .65 EC or 330ppm is insanely low... lack of micro nutrients. There are so many different deficiencies I am seeing in your pics, it has to be your nutrient level and possibly PH balance as well.... Here is the thing, you can fix this but those leaves that are affected will never get better, but may just stay the same.. You will only be able to tell if what you do fixes the problem in new growth.

You will get much better responses if you start your own thread in the "Plant problems" sub-forum.
Too many asking for help in the same thread always gets confusing.

If you need help starting a thread, let me know & I'll walk you through it.

Grew a 20oz plant earlier this year with the last month or two being around 300ppm. Hannah conversion. I never understand why everyones so high on ppm, mine don't ever want it that high. It may just be the difference between other factors in our setups.
