Is this potassium deficiency? Or nitrogen toxicity?

yeah both. Nitrogen excess can create potassium deficiency, bear in mind. Too much N will block usage of K

Did I give too much fertilizer??
So I decided to add in some soluble fertilizers. I gave it a 1/4 tsp (50% of recommended dosage) a couple days ago and noticed some yellowing of new growth on the bud sites. Is this a sign of excess potassium and phosphorus? I gave it Fox Farm Open Sesame (5-45-19).

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Yellow leaves since 1 week
Hello my friends, More and more yellow leaves since 1 week. I need to be worry? I think it's not a problem of ph because my other plant look healthy. Maybe too much water? I just give her 2 x 0.6 liter per week and fertilizer only 1 times per week. Senescence? Thanks for help

Dying leaves
I think it's a nitrogen deficiency causing me to lose some leaves earlier than I hoped, What should I carry on doing from now on? Last watering was 0.5ml/l of Grow, 2ml of bloom and 1ml of CalMag, just recently fixing a calmag deficiency after not having any(ran out).

Feeding
How often am I meant to feed and water my plants. I do water my plants every 3 days and after every three feeds I flush. Concerned as all the bottom leaves in my grow are turning yellow but the tops are okay. I do give them Calmag so I’m not sure what the issue is here.

Leaves changing colour
What’s wrong with this plant? Put her in manure instead of soil, just read John innes and thought yeah that’s fine 😂 I’m thinking it’s holding water more than it should or else it’s a PH issue. Help please? How do I fix it or stop it getting worse?
