answered grow question 4y ago
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.

Discoloration on new growth
Both of the Sunset plants are showing some discoloration on new growth, one worse than the other. I've been watering very little and infrequently per previous feedback. Wonder if it's a nutrient deficiency. Any thoughts?

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

CalMag or PK issue?
What is she telling me? Before I was thinking of a CalMag issue (upper leafs have "burned" tips and get yellowish). So I added it to the reservoir. Is it CalMag or maybe a PK issue, that resolves in a CalMag issue? See my diary for more details.

Correcting some things
My buddy is showing some deficiencies, might also indicate not right pH values. Should I wait for the soil to completely dry before correcting the pH or should I flush right away? Also why does it take 4 days for the soil to dry? I always make sure she drains every time.
