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

Nutrient Deficiency
Is this a PH issue showing or nutrient deficiencies (possibly caused by bad PH anyway, at 6.2 atm higher from earlier in week.)? Possibly magnesium deficiency, looking at pics. Anyone confident? Been hot in tents as well but water temps kept decent about 68-70.

What is causing this?
What is causing this? It only seems to be on the older leaves and only on this plant. They’re all being fed the exact same.

Is this an expected fade and if not, how do I fix these leaf issues?
I'm growing a NightOwl auto in DWC and it's on D58 (suggested flowering time is 75-85 days). The plant is looking like it's fading (getting cal-mag and different types of deficiencies), but I think it's a bit early for that based on looks. pH is 6.06, 840 ppm, 68F water temp.

Deficiency?
I noticed this spot on one of the fan leaves. It only appeared in the last couple of days. I have been feeding small amounts of calmag and biobloom. I looked at deficiency charts but I’m unsure. What could it be?

There is some damage on the first set of leaves, I was thinking it's either due to fungus gnats which I am in the process of eliminating, or an early cal-mag issue from before I increased my nutes. Any thoughts?

Calcium Deficiency???
So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

Weird Spots on almost every leaf overnight? (Leaf Burn???) My plant developed these spots on the leaves basically overnight...
I was looking after them just yesterday evening and the plant was fine, however I did a mistake. The left plant got completely wet (i had to move it through the rain) and i did not dry it before the light went back on. Right plant is completely fine. No pests (thrips spimis etc.)
