Grow Questionscurling leaves.

curling leaves.

ganzigunnustarted grow question 3 years 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??

Too much nitrogen and underwatering?Hey guys, can anyone tell me what they want (or have too much off?) I think the big one has a bit too much nitrogen is my guess? I also transplanted them today and yesterday so they had a bit less water as usual the past days. Could that be it as well?

Overwatered cubes in hydro? Too close to the sun? or effect of having add Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?
