Looks like a ph issue. Check that first before we look at nutrients

New growth
New growth looks light green after transplanting, is this normal? I don't think the soil lacks nutrients, the plants also get enough light.

Leaf discoloration cause
What would be causing this? Haven't been feeding that much, possible that pH was a bit on the high side but not extreme. I did just defoliate quite a bit. It seems it's only the newer growth that's affected

Pale spots on leaves...
Hi Everyone, I've noticed a couple of pale slodges on my older leaves. Picture in gallery. Is this nute burn? Or is it a sign I need to up my base nutes? Or maybe it's a Mag Cal Def 🤔 Hoping one of you grow wizards can help as this is my first grow ☺️

Is this a symptom of spider mites or something else?
Is this symptom caused by spider mites also, or is this a different issue? There is pale green/loss of color along the veins of two leaves. I’m aware of my spider mite problem, but want to know if there is another issue or just more symptoms of the mites.

Anyone know what's up with my OG kush?
It's quite a light green and some of the leaves are showing damage/poor health as per the pics. Under feeding? Though some of the tips of the leaves show what I thought was nute burn.

Spotted Leaves – somethings wrong! HELP!
(See previous question as well) The girls are getting worse 😬 Only the bottom leaves seem to be impacted though. Only thing I've done today is water them (three day since last and they were dry). Any suggestion to what might be wrong with them?

Burnt leaves?
Why do you think the bottom leaves look like burnt? Leaves are pale green. Only fed with gaia green 4-4-4, some locally purchased FAA and FPJ. Rain water pH’d around 6

Do I have an (Mg) issue?
Leaves turn light, have black spots and 1 leaf rolls in upwards. It got Epsomite with every watering so I guess it's not a deficiency. Last time there was not even a drain. So maybe nutrient absorption is blocked? Should I flush? Is it to stressfull for this autoflower?

Is This Mildew On My Leaves?
So I mentioned these pale colors on my leaves in my last question. (Please see last photo in Week 3). I have made a mistake - after scraping the leaf with my hand, it is definitely something on the leaves! Does it look like mildew? I removed the extractor fan for 1 day.

Single brighter/yellow leaves while flowering
Hi fellow growers, Again I have to kindly ask for your help. She's in week 7 now, the 2nd week of flowering. I've noticed only the two largest leaves to shift towards a brighter green, almost yellowish. I'm hoping it's because of the flowering but I'm far from sure. Thanks
