Nitrogen toxicity ?
DrJekyll_MrKushstarted grow question 10 months ago
Hello,I think I have a nitrogen excess, but I never had before.I see those tips going down, but leaf itself is quite good, except for this darker green. Leaf is not so dark, I've seen pictures on internet darker...but on 3 plants, this is the only one with this problem.

Nitrogen toxicity is shown by dark green leaves, which can have a leathery feel, and can be shiny. They will then start to claw downward, and in. The plant is question is getting too much nitrogen. Nitrogen can hinder bud development in flowering. The npk ratio is 1-2-3 in flowering. I would reduce the nitrogen given by a lot at this point to avoid further issues.

Hello friend, try reducing nutrients to 1.3-1.5EC max, i will also flush with 0.7EC solution before applying new strength, just in case if you have nutrient lockout (K) and reset medium, Haw much runoff you have when watering and what EC strength is runoff?

Hey man
So, reading your comment.
2.3 EC is WAY TOO HIGH.
6-700ppm 1.2-1.4ec will be the highest you'd want to get to.

Living soil and rain water problemHas using rain water killed my living soil?
Has anyone got experience of using living soil with rain water? Apparently the ppm is too low (just like RO water) for the plant to take in nutrients.
So basically is my living soil now just soil or is the microbial life still there?

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance.
Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

Black spots on leavesBlack spots present on some fan leaves. During ~3rd month right now. Watering with HESI in Coco Coir, PH ~6 every time, 1/2 runoff water.
For about 2 weeks prior to this, I also added very small amount of kelp powder.
Soil seems fine.

Leaves have developed "claws" at the tips that bend downwardsMy leaves have developed "claws" at the tips that bend downwards.
I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate)
Now my question to the professionals: what can I do to fix the problem?

Curl and clawing,N-Toxicity?Flushing?Hello Growers!
Last week I gave around 1ml/L BioGrow in 600ml water. Now all leaves seem to me dark green. Some are disformed/wavey and show burned leave edges and slighty burned Tipps. Two of them seem to be handling the high nitrogen. But the third is curling/clawing. Wdyt?
