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.

So I'm two weeks into flower now and my leaves are getting burned tips (I'm guessing nitrogen deficiency due to the light green of the leaves or some lock out) leafs are also curling upwards :/. And some fading on some lower leafs. Using biobizz roughly 10ml each Any ideas

Nitrogen deficiency in clone transplanted 9 days ago?
I just grabbed a few clones last week and Immediately transplanted them into 2 gallon smart pots with ocean forest soil. I’m confused because it looks like the plant is nitrogen deficient which shouldn’t happen within a week of going into ocean forest soil correct? I also watered

leaf tips #2
Hi, continuing the previous question. pH runoff was 6.1 So I decided not to flush and gave it CalMag. Since then yellow tips doesn't spread any further, but the fan leaves on lower branches become fully yellow and died. Does that mean problem is getting bigger and I should flush?

Leaf fade vs. deficiency
Hey everyone, does this look like a deficiency? I’m in week 6 of flower, I had half a week of high temperatures and I’m sure she was affected just a bit and noticed Bud growth slowed slightly. Not sure that influenced this and if it’s a deficiency(magnesium?) or normal leaf fade.

Light colored sugar leaves
I'm at the end of week 6 and the plant is looking healthy overall but there are some bud sites that have some sugar leaves that are developing with a lime green color. Im thinking I might have been a little high on the ec so I backed off a couple days ago. Thoughts?

Deficiencia de calmag/nitrogênio?
Boa noite, o que se passa com ela? Deficiência de calmag/ nitrogênio? Também tem estado muito frio pra strain Gorilla, será que se vai aguentar? O pH do runoff está dentro do intervalo. Tenho esperado quase uma semana entre regas porque a temperatura com luz ligada ronda os 20°

Day 20 Flower. Leaves curling
Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Yellow spots on lower fan leaves
Hi Growers! First grow here and I am 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 deficiency? N deficiency? Too less water (100ml every 3days)?
