Leaves looking f’d?

GardeningDougstarted grow question 5y ago

What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Could be light burn from ur grow light being only 8 inches away. I know its lower watt but still 8 inches seems rather close to me. I'd back the light off to like 12 inches. Make sure to check ur mediums ph after u water with 6ph solution. Ur ph could be off causing ur necrosis. Happy growing and stay lit fam.

Looks to be calcium deficiency, or light / heat stress. Looking at your diary 8in away from canopy might just be light burn . Back your light off just a bit or add more air flow to the top of canopy.

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!

Small brown spots on certain leaves Some leaves are showing small brown spots. Around 5% leaves affected and all are close to each other. Can this be an infection? Otherwise plant looks healthy

Was haben meine Pflanzen?Liebe Community, Neuling hier :) Ich habe zwei Critical Kush Auto in der 7ten Woche die seit der Blüte eine leichte Nekrose/Verfärbte Blätter haben. Leider habe ich vor 3 Tagen erst das erste mal mit Hesi Bloom gedüngt 5ml/L, vorher noch garnicht. Mehr Düngen? weniger Licht?

Condensation, CalMag, Nute Splash?Twice between heavy defoliations the were leaves were so jammed together some leaves would get wet from contact with other leaves. It's the only leaf on the whole plant like this - as of now. Seems like Calmag? Product of sweating? Nute splash? (week 7 photos)

Deficiencies? Brown spots, yellowing and purple stems What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Would putting off my first feeding for a day or two do this much damage to the plant? I've given it 2 feedings since then and hoping it's on the right track as the new growth is nice and green.

brown spots sugar leaves I've asked this before, but the issue still seems to be there though it's very minor. Some of my more developed buds sugar leaves are showing brown markings. Last watering I flushed her but the markings seem to be spreading still, although very slowly. What am I dealing with?
