I'm starting to see my upper leaves turning a bit yellow in spots. I think I may be over watering. I've added 1 gallon water to 3 gallon pot leaves looked to droop a bit.

Light green "splotches" on leaves
Hi, I've noticed light green "splotches" on my leaves which I'm having trouble matching with images of leave problems. Doesn't appear to be impacting on growth and the issue is only visible on close-up so it might just be me being over concerned, but I'd be grateful for advice!

Is it infected?
Is it infected, like mildew, or has it just some nutrient problems in the beginning? And the leaves form is just the genetic i guess?

Discolouration of some leaves
Is the colouration of these leaves someone to worry about? She’s a young, 2 week old Wedding Cheesecake auto and I’m new to growing and just want to make sure she’s ok! She’s growing in a 70/30 split of coco and soil and has only been fed water so far! Is it nute time?

Plant #1 is showing some leaf discolouration. Not sure if it is nutrient burn/lockout or deficiency. I flushed her with R.O water just in case. Any ideas or suggestions? She's an odd one anyway, seems to be a different phenotype than her sisters.

Possible rust on Auto orange sherbet?
First time with this strain, Auto orange sherbet from fastbuds... Soil pH is 6.5, soil test showed good amounts of NPK...we do have a natural magnesium surplus in our soil, but it never causes issue, sprayed with neem and Arber... Looks like rust?

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.
What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Noticed small brown spots kind of center of leaves, noticing some kind of chewed up deformed leaves now. From what I've read it sounds like leaf hoppers? Has anyone else had a similar experience?

Nutes too early?
The leaves of my northern lights look a little brittle and discoloured, maybe the small amount of nutes I gave were too early?

Is it CalMag deficiency?
See week 7 - small spots have also appeared on the leaves, resembling a CalMag deficiency.This time, before starting the grow,I mixed approximately 3 tablespoons of dolomite lime into the soil, but apparently,it wasn’t enough.Do you think it’s time to start adding Biobizz CalMag?

Curled leaves occurred in both veg and flowering tents only to my purple trainwreck plants. Checked leaves with a loupe and couldn’t see signs of any pests at all. Only occurring on my PT plants in all tents. Other strains seem 100%. Only on large fan leaves, any ideas or help?

Copper/Dark purple dying leaves
Weird copper/dark purple colors on greenhouse plant leaves. Do any of you k ow what type of deficiency/ toxicity/ root problem this can be ? Closest I can think of is Phosphorus deficiency but I cant pinpoint it. Any help from someone who might have experienced this will help🙏🏻

Slight discoloration in the leaves
The leaves are starting to get slightly discolored on the edges, what could be causing this? Could it be the white flies? Or could it be too many nutrients? I am giving the plant a bit of Canna A and B, although it's meant for hydroponic, it's all I have at the moment.

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.)
