Can I fix this? Kinda looks bad.
I think effed up... Not exactly sure how or how bad it is. I haven't fed in a bit and looked like a nitrogen def starting, so I fed half strength, and 48hrs later I have this. Can I fix it? I did fish water this morning. Calcium def?

Underfeeding?
Beginner grower here. Had some issues with underwatering and it's slowly recovering. Now am unsure if yellowing leaves are signs of underfeeding as it's still early in flower or due to the underwatering. Bottom leaves yellowing and dying off too. Using GHF Bio line as recommended

turned yellow, what's the problem?
The big burdock at the root started to turn yellow a couple of days ago, the tip is drying and bending. This is a deficiency of phosphorus and potassium on the 45th day from the nut (7th week) - or am I wrong? How to fix it?

4 days without water
I had to leave for 4 days this past week. Gave both plants H2O before leaving but I came back and one of my plants has some ugly yellow and brown leaves. Do I need to do anything to correct this or just get back to my routine feedings?

Yellowing first leaves - CalMag ? Bugs?
Any suggestions on the yellowing first leaves issue #Day19? Is that a Cal or Mag def ? Been watering with tap water left for 24h. Would RO water be better ? Does feeding with RO water on the entire life cycle involve to add more nuts ? I currently have only AN micro/grow/bloom.Tx

Having some discoloration on the fan leafs. From a quick Google it seems to be related to nitrogen deficiency. Would adding some coffee grounds or other organic matter quickly reverse this?

I think it's calmag and lack of nitrogen but any ideas. I've been busy in the garden so have taken my eye off the ball. She looks in great health with praying full leaves but her colour is off. Any ideas would be taken with gratitude.

Only Fan leaves starting to turn yellow?
Why are only the Fan leaves starting to turn yellow from the outside inward? All other leaves are okay and green. Blueberry Auto 10 weeks old, organic soil grow. Should I remove? Comming up on the flushing period soon.

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
