Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

Spots on leaves, brown shimmering.
I've read that it's a boron deficiency, but I'd rather be sure.

Having persistent yellow/brown spots on my leaves. Took a close up picture to show them better. I adjusted my nutrient schedule to increase phosphorus content. pH is checked daily. What else can I do to eliminate the problem?

Are these leaf changes normal?
This is first grow to make it this far. I am unsure if my leaves are just doing their thing; or if I have a problem. She is an auto-flower. I am on day 74 from sprout, day 35-ish from flower.

Am I correct in diagnosing this as Calcium deficiency in the Black Sugar? I gave a basic compost tea yesterday. What else can I do to ensure she makes it through harvest?

should I be worried about those little white spots, do they indicate on some kind of deficiency or they will go away eventually by themselves? I mean there aren't much but still, got me little worried.

Light spots on upper leaves
So I noticed some light spotting/discolouration on the upper leaves of Samus. I've never seen anything like it before but is it normal or something to freak out about? Are the leaves mottling?

On my NLxBB there appears to be rust spots developing on both sets of the first true leaves, i've only fed nutrients once on Day 10 and that was at quarter strength. Not sure if this is a sign of overwatering or if I need to start feeding with Cal-Mag more regularly.

Leaf browning, yellowing curl one day change.
Over night my plant went from looking good with maybe a calcium deficiency to curled leaves looking very soft and drooping. I sprayed with insecticidal soap, but in the past no harm. It is growing outdoors, 30c 60% humidity. Any help appreciated. I sprayed with kelp today.

Leaf Spots, weak color, and leaf ripple
Please help me identify possible causes of this: small spots on leaves, minor color fade (not burn) along edges, and strange 'ripple' effect. A user commented that he thought my plants looked deficient but hasn't elaborated further yet. What might this be? Multiple issues?

Calcium or Phosphorus Deficiency?
One of my 3 Cream & Cheese has upper leaves on 3 stems/colas per the pic. The lower leaves are OK, the other 2 plants are fine. Thought calcium at first as phosphorus is more lower leaves? Maybe just add CalMag? Thank you so much!!

Spots on leafs, and lime green tops
I am beginning to see leaf damage again, so i would like to ask if you guys could point me in the direction of my problem. I suspect either light damage, or ph issues building up over time. It started before i gave the first flower nutes, tops seem deeper green since that though
