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.

What are my leaves telling me?
Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

Leaf discolouration. Nutrient deficiency?
Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

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.
