Looks like overfeeding/nutrient burn. I'd suspect potassium toxicity due the the yellow/burning tips. Thin new growth and ur large bloom feeding u just did. Dial it back fam. In most cases with cannabis less is more. Happy growing and stay lit fam.

Yellow and burnt leaves
Yellow on one side and pretty much green on the other. Why? Lol I'm light on the nutes. I dont think I've been giving to much. Maybe not enough? I hope it makes it.

Your opinion?
Today flushing the wedding cake i was thinking that the problem was an excess of nutrients, but instead water was quite clean, around 1100ppm at the first drain, after several flushes water is now on 600ppm. I also raised the lights.. I still do not understand 🤔

Yellowish color at the tips and wrinkles
My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.

Yellow tips
New grow, new leaf colours! I think it could be over feeding, but would like to see peeps opinions if possible. Have stuck to the feeding schedule, but the fabric pots might be making things more complicated somehow?

Feedback/checkpoint/thoughts
Hi every1👽😌Started week 7 of flowering today. How do they look to you? Is there anything I should pay special attention to? I think I may have overfed or overwatered them last time - I’m not sure which one - which could explain the leaf damage. What do you guys think overall?

Yellow leaves black tips
What’s happening with this plant? After watering all my plants 2 days ago, one of them has been quite droopy and developed these yellow areas with dark tips. Is it a watering issue / heat / deficiency? Thank you

Lack of or abundance of nutrients?
Shes doing really well but I noticed some of the leaves starting to get a little yellow so I stopped giving her nutrients and have just been giving her water for at least a week or two. She still acts like shes getting too much though? GDP auto x gumberry auto is the strain.
