It’s definitely over feeding. You should give them only water for 2-3 weeks or give them a good flush if it doesn’t stop and keep spreading. In soil, nutrients gets used up after 3 weeks approximately. When the EC of the media gets too high it turns into hypertonic condition ( and pH start to drop dangerously ), the plant start to reverse her fluids to dilute the roots zone to turn it back into a hypotonic condition to balance the fluids exchange. This is why your tips gets dried and burned !

'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 fI'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. 😓

Discolored, burnt and curled up tips on higher leavesSeveral symptoms, always on tips of higher leaves : they are discolored/burnt or burnt/curled up. LED @40cm (deemed 70% of 300W) and I just gave them the 2nd flowering feeding, 4 days after first one (pots were very light). I was planing to start compost tea... What should I do ?

Veg crisis - Auto Blueberry and Strawberry bananaHi,my plants are in the middle of a crisis. I’m thinking i might’ve over fertilized them, (fish mix-biobloom 2ml per plant in 1l water). Can someone help me identify the problem and help me understand how to fix it? I was thinking maybe a zync deficiency. Thanks!

Heat or excess fertilizer?I'm not sure if it's overfert, heat or both together. It's been almost 50ºC in the grow room and that's been a problem. I decided to supplement it during flowering with Biobizz Biobloom and I believe that overfert occurred, many leaves were completely dry or burned.

Dealing with Nutrient Burn and Salt Build-UpI've observed salt build-up and nutrient burn in my plants recently. I've taken action by flushing and removing 60% of the affected leaves. Now, I'm considering whether to remove the remaining affected leaves and when to proceed with top dressing. Please advise.
