Are you using 5ml per gal of Cal-Mag Plus? If not that's possibly the reason. Keep in mind all my plants from all my grows have at slight almost un-noticeable brown tips. It's fairly normal.

You are experiencing a nutrition burn.

UPDATE: I dont think its nute burn as my ppms when feeding are low. It may be light stress so im gonna lift the LEDs which are about 30 cm away right now.

Louderanswered grow question 3y ago

Usually means nutrient burn or light stress. What EC are you feeding? Are you using LED? How far away from the fixture is that cola? I'd lean towards the light being too close/intense since you said it isn't happening anywhere else

Over feeding.

That's either potassium deficiency or generally too much water. Since it looks pretty healthy otherwise, I'm going to guess potassium. Nuts1

Light or nutrient burn?Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?

Suspected nitrogen toxicity?Does anybody have any insight and suggestions for what's going on with plants 2 and 3? I'm treating them for suspected nitrogen toxicity, feeding them calmag-only water. Their runoff EC is still 800-1100 though, which is below influent EC.

'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. 😓

That looks like nutrient burn in the last picture, right? Should I be doing anything other than dialing them back?

Flush or what to do ?Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦‍♀️...or it is it rust?

Yellowed tips good evening guys the tips of the leaves (40%) show signs of yellowing and dryness (only the tips). i read that it could be overfert or too much water. I've also read about lifting from the pot (done), checking the roots (healthy), letting the plant breathe out, cleaning the walls of the pot, and replanting. it should be enough? do you think they are the rig… Show more

What gave this? Light excess or nutrient burn or lack?I had this symptom from the beginning, stable, I didn't worry too much. What could be the reason? How to avoid this in the next grow. I mean, it's minor, but might be better to attend and unleash a better result. I have this on all buds, on canopy it comes with curly leaves.
