You are experiencing progressive potassium deficiency. Light nitrogen and heavy potassium are phosphorus in flowering. Good luck🌱

Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Leaf discoloration. 5 weeks old
I transplanted these girls 2 days ago and have started them on a new nutrition. I’ve noticed some discoloration on one of the leaves today almost sure it’s the nutrients. Can someone help me figure the best thing to feed my plants? Thank you (nutrition diagram on my first diary)

Black tips and spots on the leaves
I'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

Discoloration bud leaves
Anybody know what this discoloration is? Humidity was a bit too high so I'm hoping not some type of mold. The affected buds did get quite a lot of wind and light, so it might be light- or windburn? Any help appreciated!

K deficiency? Or something else?
Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?
