What is causing my leaves to turn dark and dry?

bildostarted grow question 6y ago

I'm growing 3 Gelato #33 plants in a DWC 5 G bucket setup. Same conditions for all 3 plants, but one of them is experiencing dark spots on the leaves and now they are beginning to shrivel up and dry out. The newer growth looks okay, but might not last long. What can I do ?

Hi @bildo It seems to me to be over-fertilization, it decreases the dosage. you can also see marks of PH variations on the leaves. good luck mate 👍🙏

Which pests do this?Exactly what pest does this kinda damage? I have my guess, but wanna get other growers' opinion on this type of yellowing of leaves and brown spots. 6 weeks into veg. It started very early on at bottom leaves, once I trimmed them this brown spots appeared on top growth.

What's the cause of the curly twirly leaves?What is the cause of the curly twirly leaves? I am thinking it could be the cold nights. I have a heat-mat in the tiny greenhouse, but still it can get minus 10 Celcius in there. Watering, could be? The Dinafem OG CBD Auto does not seem to be affected by this. Thank's in advance!

Spots on leaves Anyone know what's causing this? Slight discoloration and rust spots, mainly on older leaves. It's not that bad but quite spread out. did spray with neem oil recently, so is it just burn spots or a nutrient problem?
