Foglia bruciata

PeppeItaliastarted grow question 5y ago

Al mio risveglio una delle piante ha una punta di foglia secca bruciata. Uso un led da 300w. Altre due piante hanno solo le punte delle foglie superiori leggermente gialle, solo piccole punte. Troppi nutrienti?

Looks to me like a Potassium deficiency on that leaf(if near bottom of plant). Where on the plant are those pictures? yellow/brown tips can be either nutrients or light burn. Light burn usually has twisted leaves.

Do you think the yellowish leaves are because of nutrient deficiency, a nutrient burn, or just her fall colors?

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt f I'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓

Yellow edge with brown spots on fan leaves I am wondering if anyone could help me figure out what is going on here. She’s been healthy all grow, but in the last week has started showing the weird yellowing/browning on a few leaves. The temps, nutes and light haven’t changed really. Anyone have any idea what this could be?

Is my plant giving a warning I'm not sure if I have a problem or it's normal. Some tips show damage I think it was the light to close so I moved it back over 12 inches away. I am giving the bloom every other day but half of the water i give. No nitrogen is being given,hardly any ever she doesn't like it.

Rust/dead spots This girl, was overall stressed out from the beginning. Lights, overwatering, ph , wind burn, you name it. Either way all of the plants have long recovered. Still stunted tho. Plants have only received one 1/4 dose of veg nutes. Are the spots from lack of P and K?
