Leaf discoloration - light and dark splotches

Hello! Any ideas as to why my leaves have splotches of discoloration? 😅
It appears that one leaf has light 💀 patches while the other leaf has dark. 👹
Thanks for your time! 🙌

Hey friend,
So 2 things come to mind. 1 calmag...i had many plants get rusty spotty leaves until I regularly used a calmag supplement. 2 by any chance are you misting your plants? I used to do this to boost moisture since I live in the desert and the chlorine in the water etc caused some serious spotting...I finally figured it out and stopped doing that. And now i only do a foliar application at lights out.
Happy growing. ✌️

So going based on your diary this could be a few things.
1) Is it at all possible that nutrient water was spilled on that plant? It looks like it could possibly just be residue from nutrient salts.
2) I don't see any calmag supplements listed in your diary. Are you using any? In hydro calmag is a necessity and a calcium deficiency in it can start out with some light spots like that. On top of that, it is a good idea to feed a light dose of nutes in hydro once the first true leaves develop or growth will slow down.
3) Your PH is in range for hydro, but it is at the very bottom of the range. Calcium is absorbed around 5.8-6.0 PH. I wouldn't go above 6.0 PH. I grow in coco which is a hydro medium and started noticing some issues when my PH drifted to 6.1 or above.
If you need any more help/advice feel free to message me! Good luck!

Did I go too light with the nutrients this time around? Yellow leaves and fading pretty quick. A good dose of nutes next watering?My plant has about 3-4 weeks left, I have always had nute burn so I went what I think was way too light w the nutes this time. Is this a nitrogen deficiency along w calmag deficiency? I'm in week 3 of flower, should I give a good dose of nutes next watering? Advice appreciated.

Growing in FFOF with some HF but have nutrient issues...have only given CalMag with RO water and this is what I've got.Wedding Cake nute burn or possible P deficient with yellowing slightly down the edge?

Leaves fading and dying, started from bottom but spreadingI’m starting to be at a loss with this. Calmag issues earlier in veg, seemed to improve for a while but now bottom leaves started to die - I thought this was just due to beginning of flower but it’s getting worse and spreading even to healthier new growth. PH (should be) fine.

Leaves changing colourWhat’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?

Underwatering Issue or something else?I haven’t been tracking exactly how much I’ve been watering. I usually water until run off. I’ve had to water daily because the coco loco has been drying out quickly. Is the yellowing seen in photos from 4/28 due to underwatering?
I’ve been pHing between 6.2-6.4
