Is this potassium excess or deficiency?

I had originally coined it as deficiency but when I started feeding at full strength for the last 3 weeks and only seeing a general progression amongst the leaves , be it a slow progression . But its clearly persistent . And I'm starting to question whether this is phosphorus deficiency or whether I'm feeding too much .

I'm at full nute strength using ghe terra aquatica.

What do you think ?

Phosphorus or calcium deficiency. It's not burn or all leaves would be affected. The two can appear the same. I'd cut the nitrogen totally and give a good bloom feed. Dark green says enough nitrogen which might be what's blocking either or both.

I'm noticing with the other 2 plants they are starting to get a bit lighter even though full feeding of npk . Maybe flush next round followed by full strength feed . But leave the nitrogen darker on the darker plant

Terra Aquatica is the General Hydroponics 3 part liquid nutrient right? Is this soil or soilless media? How often do you feed and what PH? Also, do you feed to plenty of runoff, or just enough to moisten the media?

It is its grow micro and bloom . I feed about every 3-4 days . pH 5.8-6.3 , what i do I water with a litre of pH water ,then 2 litres of pH treated nute solution plenty of run off about 20% from nutrient solution

no need for water first before nutrients. i understand the thought behind it, but it is unnecessary, extra work. runoff is good

what ec are you feeding at?

I would say it is a good idea if you let them dry out to much before watering. I found it to cure my burnt tip issues is I was letting soil dry out to much before watering again and then using nutrient water on top of dry roots. But if watering properly then no need.
