What could be the reason for leave tips curling down (claw)? Besides nitrogen overfeed? Are there any other reasons for that?
Happened on a couple girls, not all, but they were all feed the same.
No diary = no information. Clawing is usually associated with an excess of nitrogen but can also be the result of over/under watering... without a diary and not even a photo, it's hard to point you in the right direction. One thing you need to understand is that each plant is an individual and will react to the same nutes/conditions differently from another plant even if it's the same strain from the same seed bank... you just need to learn to read the individual and give them what they want/need.
Good luck...
you been asked to create diary, if you want help, by many growers here, still you insult and want help.
i told you pure truth, its your fault, you are the grower, nobody else. fact.
