Light burn or nutrients lockout?
Jerma_growstarted grow question 5y ago
Is this light burn? The light is a sf1000 dimmed at 60% and 65cm away from the tops. It’s around day 40 of veg I am using bio tabs so if it’s over feeding I can’t change anything. But it’s only the tops leaves that have yellow tops. Light burn or nutes problem?

EC level of the soil might be a bit too high, probably because you’re not pouring enough water during watering. Try to get about 20% of drain from the pots.

White Widow runoff water tests at 2440 PPM, but seems happy still and is only showing very slight signs of burning. This still seems extremely high, so I've backed off on feeding for now and watered with some Cal Mag. Should I wait for the PPM to drop or keep feeding her at 1/4?Week 11

How to handle minor nutrient burn?I have some minor nutrient burn forming and am about to trust a friend with feeding her for a week. Do I have them just do ph balanced water? Or a lesser dosage? I don’t want to have them feed nutrients unless y’all think it’s absolutely imperative.

Help with burned leaf tipsThe tips of some of the leaves have begun to dry, curl, and look to be dying (see pics). I think it's some sort of nutrient burn, but I'm unsure. I water every other day w/ a solution of Miracle-Gro 24-8-16 at 50% recommended concentration. Used distilled H2O last 2 waterings.

Banana Purple Punch Auto RF3My current diary for the plant is on my profile. I've had slightly burned signs on new leaf tips for a few days now, and on some leaves, the tips are even drooping. I can actually say it's not overwatering or nutrient overload.

'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. 😓

Yellow tips of leafs …Overfeeding? Yellow tips starting on top of the plant … should flush or just wait and reduce the feeding next watering? I‘m entering the pre-flowering stage and would normally start to add bio bloom and top max with the next watering …

Leaves tips look burnedAny suggestion of how could make her look healthier? Tips look burnt and leave color is not great. Also my plant is very short, 25cm. I didn't feed her any nutrients so far, only water pH6.5. The soil (atami kilomix) was heavy fertilized with bat guano. Is she needing something?

Is this due to the sun and hot weather?Some parts of some leaves are looking like they're burnt or something.
Is this due to the sun? Or do I have another problem?
It has been extremely hot last week (around 35 degrees all week). And the plant has been in direct sunlight (I've moved it into the shade yesterday)
