Potassium deficiency. You are running way too much nitrogen in flowering as well. Shiney dark green is toxicity. Which nitrogen can hinder bud development in flowering when too much. Flowering NPK ratio is 1-2-3

Potassium deficiency?
Can you confirm this is a potassium deficiency? This happened after a flush of an amended soil (SoHum), please take into account before you answer. I do have some Down to Earth Organic White Azomite Powder OTW, just not sure how much to add yet.

Calcium deficiency, cal-mag now in hand, water now, or wait for normal scheduled water? Last water yesterday.
Plants are suffering from an early stage of calcium deficiency, received a bottle of cal-mag today. Watered last night cause I didn't want to wait any longer. Should I wait for my next water (2 more days) or give a single dose of Cal-mag now, to get some calcium to the plant?

Yellow leaves from bottom upwards
I have yellowing leaves from the bottom up. It resembles either N deficiency, MG deficiency or both. Growing in soil. PH is between 6.5-6.8. Feeding 1ml/L fish mix and 3ml/L bio-bloom every other watering. I tried adding cal-mag with N at 1ml/L and if anything it's got worse.

Does the paleness concern you?
Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

Rust spots on leaves, second grow and need some confirmation.
I'm noticing rust spots on my leaves, which I suspect could be due to nutrient burn or lockout, given the PPM is unusually high for this stage of growth. To tackle this, I'm planning a simple flush with some Cal-Mag, keeping the pH at 6.5. Does this sound like the right approach?
