Not septoria but burning from severe nitrogen toxicity would be my diagnosis. Feeding too much or too often (or both). Not watering to run off each time can accelerate the problem.

Yellow on leaves
Day 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?

I had a ton of my fan leaves going yellow this week (week 6 of flower) and I am a bit concerned. I know its normal but it seems a lot went yellow fast. Think this plant will make it to harvest okay?

Yellow on Cotyledon normal?
Is that yellow on the cotyledon leaf normal? 2 days post sprouting and that one had helmut head the first day. I was able to remove seed pod by lightly lifting the edge of it with tweezers.

Lime green/yellow plants
Ok so my OG Ladies are looking pretty lime green/yellow. I noticed when I mixed my nutes I think I mixed up the a and b bottles I also don’t really check PH, relying on microbes to buffer. I checked it and it’s high. Iv fixed the res mix and upped the dose. It’s been 24h ish…

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Yellow leaves
Hi there, I have a Skunk #1 Auto plant, about 7 weeks old, at the starting of the 7th week some leaves started to turn yellow. I read two options, that it is an N deficiency, the other option that it is normal as the buds absorb the N from the leaves. Any ideas?

American Cookies 1st grow - Nutrient Deficiency fixed? What about my LST with budclips?
What’s up? Updates on my previously unfed American Cookies: Looking better IMO, what do you think? Is the lack of nutrient fixed? I also did an LST with budclips on it to help utilize the space a little bit better, did I do it right?

Leaves yellowing
These leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?

What nutrient deficiency is this?
What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Yellow tips on newer leaves. Nutrient burn or something else?
I have noticed yellowing on the tips of newer leaves that seems to be slowly getting bigger. Nothing on older leaves. Start of Nutrient burn? I also have noticed some yellow/brown spotting on older leaves but that may be related to earlier PH flux that has since been fixed. TIA!
