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.

Why is this plant more yellow? Nitrogen deficiency? It’s been having issues like this the whole grow. Ph of water has been a steady 6.5 -I top dressed with some bat guano 10-3-1. Will that fix it?

Strange coloured fan leaves (3) on one of my 4 plants, maybe some sort of deficiency? Thanks people!
Hey there smart people! I have about 3 strange coloured fan leaves on one of my 4 plants and I’m not really sure what to make of it. To me it doesn’t look like any deficiencies that I came across per say. All other leaves look nice and healthy. Kinda randomly scattered. THX!

Brown spots and yellowing
What do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.

She has yellowing and dying leaves issue for a while now. I was giving more nutes lately to combat the issue. Now burnt tips say it is to many nutes. So I decided yesterday that I should water with a bit of calmag before next feeding at beggining of the week.

Deficiency/Light Stress Issues
What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.
