curling leaves.

ganzigunnustarted grow question 4y ago

it has been four weeks now and i observed some inward curling of the leaves and shiny green colour which is i think the result of nitrogen toxicity. what do you think? im thinking to give some plain water for the next couple of times. by the way i've never exceeded 0.8 EC so far.

Looks like an N tox to me. I also noticed the leaves closer to the humidifier look in worse shape than the leaves at the back. I'd try and make sure they arent getting the moisture from the humidifier blown directly on to them as they are looking overwatered. I would be inclined to flush when shes next due a watering to get rid of possible nutrient buildup. (Pour 3x pot volume of water through) Also I'd test the runoff ppm/EC just for that added peace of mind. Hope this helps 🙂

In your case I think it isnt from the medium. I think it's the humidifier blowing directly at the leaves. They have a shine to them. Which means the will have constant water on them preventing the plants from adequate transpiration. Even if you are watering correctly the plant cant expel the water it absorbs through the medium.. giving it an overwatered look. But you are correct overwatering and under watering symptoms are similar. Hope this helps 🙂

Is the medium wet enough or over wet ?? Underwatering and overwatering can cause the leaves to look like that??

Hello weed doctors, I need help identifying the problem and gathering advice how to enhance my second grow. It's only day 29 and my girls are sick, wh I'm in biobizz lightmix. Started biogrow on D24, the dose was 50% in 400ml water. Until D24 only rootjuice. Yesterday gave 1400ml each, with 100% biogrow, pH6.4 EC 1.1. My water is hard pH7.7 EC0.8, so I wasn't adding calmag yet. There was 400ml runoff EC 1.9 - why? What do I do?

Cotyledons Twisted This happened to the last seed, so maybe it is me. I'm worried it won't point up. Second day seeding. I wet the soil when I planted and has been under a dome. I have not watered again. DLI is 12 and PPFD is just under 200. Any advice on what I am doing wrong?

Do these look healthy? Thoughts? I'm new to hydro/growing I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.
