Yellowing sugar leaves?
Does this yellowing on the sugar leaves look problematic? I know the end is near so I don’t want to do any damage this close to harvest. Think another week will be long enough? Vermiculite/Perlite/Soil @ 40-40-10% Lotus Bloom @ 1/2 dose (700ppm) 100w LED 14” above canopy

Brown Tips on some leaves - too much nutrients?
Today I recognized brown tips on a few of the leaves (see pictures). Is it something to worry about? I am having trouble identifying the problem and how to counter it. My best guess is I used a little bit too much fertilizer for this automatic? But I am unsure...

Brown tips on older leafs
What indicates the brown tip of a single lower leaf. Growth is also relatively slow. I see this on my 25 days old Hulkberry Auto. The plant sits in a greenhouse on my balcony. Night temperatures go down to 8-12°C. No fertilizer used.

Always produce drain while using organic fertilizer?
I think I made a big mistake in this very first grow, so here is the question: Should I always water enough to produce some drain? Even when using organic fertilizer? Until now I did not have a single drain in the whole grow as I water ~10-15% of the pot volume.

Yellow lower leaves
Hello, This is my first grow and now I'm confronted with the first problem. The lower leaves on my plants are turning bright and yellow. A few leaves have very small brown spots. Can someone help me and perhaps have an idea as to how I should proceed? Thanks.

zu viel Dünger oder zu starkes Licht?
Hallo meine 2 Ladies bewegen sich jetzt auch Woche 4 zu, vor 1 Woche habe ich mit düngen angefangen. Ab und zu sind die Spitzen etwas gelb vielleicht weniger düngen oder zu starkes Licht? Sehen sie soweit gut aus?

Nitrogen deficiency but why?
My Critical Auto is more and more wilting and yellowing. Most likely due to nitrogen deficiency. Some have red tips on . PH of soil was normal, how can I make sure that it's not nutrient lock anyway? Should I flush it nonetheless? Feed it more? More info in my diary.

Nutrient lockout or deficiency
Die unter Planze im Bild ist seit ein paar Tagen hell obwohl ich letztes mal schon mehr gedüngt hab. Habe mit EC 1.5 / Ph 6.2 gegossen. Im runoff kam Ec von 3.5 raus, es war aber nur sehr wenig runoff deswegen find ich 3.5 eigentlich in ordnung. Blatt spitzen sind aber auffällig.

Nitrogen deficit?
The bigger plant is struggeling a bit again. After some talks and readings it could be a nitrogen deficit but am not really sure how if I should react to it, since the need of the plant should get less for nitrogen in the next weeks. Please read my journal for more information.

Brown spots on top leaves - nutrients, light or something else?
She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves. I suspect this could be light burn or nutrient related. Any ideas? Pls help

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

Bottom leaves yellowish - why? And can I top?
On both of my plants (C99 & S.A.D.) the bottom leaves are turning yellowish and I can't figure out why. I'd also like to top them this week (above 3rd node), but I'm hesitant because of the leaves. Any advice on what they may be missing, and whether I should wait with topping?
