Nutrient burn or nutrient deficiency?

MylesJM · Aug 23, 2024

Just wondering if I have some sort of burn or a deficiency

1.4 EC
This is week 3 flower
On a drip system always getting run off

Took the plant out of the tent an hour after lights came on and slowly watered until I got run off, fed plant with 1 litre of nutrient solution and got 180ml run off. The EC of the run off was 1.5 so only 0.1 EC over my input which I wouldn’t class as concern.

I’ve raised my lights in suspicion they could possibly be getting too much light as I’m not getting any of this on the lower bud sites.

Thoughts?

I agree with your actions on raise my the light to be safe. I would wait for those with more experience to voice their opinions. What nute line you running?

I’m using shogun. I believe it’s a Europe brand

Would I experience burn on the lower growth at the same time? Or would the tops burn first?

That one is beyond my level. I believe it would depend on the specific nutrients for the manifesting of symptoms.

Here is another picture of a different plant that is maybe 6 inches smaller than the one I sent

The tips of your leaves don't seem like terrible burn to me. But my experience is limited. I know I had something similar that was not a terrible set back. I had slightly yellowing tips on parts. That's a better pic. You feed with RO water?

Could be time to add cal mag to your girls feed. That's super common.

I agree they’re not terrible but i would want them to be as close to maximum health as possible which I understand is always going to be a battle and no I am using tap water

I’m already adding a small dose of it so really unsure what it could be

Hopefully raising my lights will help lol

Yeah in coco, every irrigation I do produces run off so the salt build up only really happens over night, and 2 hours into the lights on I hit them with a multi feed every 15 minutes until run off is achieved.

1 minute and 30 seconds my pump is on for every 15 minutes until run off is achieved. My run off is only reaching 0.1 EC on my first batch feeds over my input, maybe I should cut back on my maintenance shots to maintain almost saturation during the lights on to promote bigger dry back?

I'm betting this was the start of light burn since only the tops were affected. Nutrient burn usually starts at the bottom of the plant.

I’ve been searching for this information all day, every way of wording “does nutrient burn stsrt at the top of the plant or bottom” and the search result always came back as “it starts at the leaf tips”

I know it starts at the leaf tips ffs but where on the plant first
