If its just the lower leaves it may be from getting them wet when watering.

Yellow spots on leaves
Hi Growers! First grow here and I'm concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg def? N def? P def? N tox? Too less water (100ml every 2-3days)?

Yellowing copper leaves late flower
Harvest is coming up soon and I have noticed some of my leaves mostly the bottom but some on top also have started to turn yellow with brown/copper spots. I believe it is cal mag deficiency, will this mess with my yield or quality of the bud?

One of the plants doesn't look so good, looks like is related Cal/Mag deficiency but I added it after 10 days from seed so not sure if I had to add more or is something else. Any clue about it?

Are they still looking overwatered?
How are my babies looking? Watering now every 24h (0,5l) and I raised the pots so they no longer stand in the runoff (doh!). The calmag also arrived today so hopefully that will help my Green Gelato with the yellowing 🙌

Yellow tipped top growth
My plant has had these yellow tips for a few weeks now. Seems to only be affecting the top leaves and doesnt seem to spread any further than the tips. 3 weeks into flower and her buds aren't fattening like my others. I added more P. Any ideas? She has plenty of micros...

I think I have nut issues?
OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?

Yellowish Spots on Fan Leaves
The fan leaves on one of my plants are getting yellowish spots. I noticed it yesterday and checked the pH and I was at 5.0. I corrected it to 6.0 and 24 hrs later still 6.0 but some of the larger leaves are starting to show yellowish spots as well?

Yellow tips
Dont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore? A other reason could be light burn. But with a distance of 50cm I dont think so
