Yellowing Leaves? Nutrient deficiency? Fixable?
Is this a nutrient deficiency? I'm 3 weeks into flowering. 2 or 3 weeks away from harvest. I'm using Biobizz Grow, Bloom and Top Max. Is it an issue that can be fixed? Or do I just need to get it right next time?

Yellow leaves
Hello, take a look at the pictures please. Leaves are turning yellow and curl. Is this a N burn, or a deficianty from some mineral? Or is this nutrient lockout? Plant does grow well!

I know it is normal for the leaves to yellow in the flowering stage but it is only 3 week and 5 or 6 leaves become yellow on the bottom should i use more nitrogen to prevent it or let it be ?

Yellow Leaf Tips with Brown Spots – What Could This Be?
One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas. Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

I noticed that some leaves have turned yellow due to a lack of NPK. I'm halfway through the sixth week and I'm only feeding the plants with Biobizz Top Max. What do you think if I add a bit of Biobizz Grow??? Thanks in advance!

What's up with the yellowing leaves? They seem to yellow from the outside inwards and the tips also seem burnt too. Is it nutrient burn? Excess or Deficiency? It's mostly on the bottom but its affecting some of the bigger leaves in the middle too, Watch the video for an overview!

Balcony Auto Gelato with Yellow and Brown Leaves
I'm growing this auto gelato in a balcony safe from rain fall and harsh wind, it's the 25th day and the bottom leaves and cotyledon are turning yellow and with some brown traces. I started to use minimum amount of "all in one" fert. Do you think it is overfertilization issue?

Is my plant showing signs of Nitrogen deficiency?
Autoflower, day 40. Most leaves are in a yellowish-green tone or even completely yellow. I was mistakenly watering it with tap water, but when I noticed the yellowing, 1 week ago, I started watering with mineral water at pH 6.49.

Do you think the sudden yellowing of the upper leaves is due to the flowering, or does it indicate a deficiency instead?

Deficiency or light stress?
I start by saying that the light was not close enough to cause stress imo.. was about (30cm) of distance from this plant. it seems that it is more a deficiency in my opinion but I don't know exactly which one.. What do you think about that?
