Not sure what’s going on

[Dreco]

Almost all the tips of my leaves seem to be burning and splitting and the plant has seemed to slow down growing. Kan anybody tell me what’s going on?

2x6 grow tent with 2000wled lights, a pretty solid air system and a humidifier. I run a 18/6 light schedule, water 2-4 days apart. 60-70% humidity 74 degrees temp. Organic water only soil, currently lst

Looks like maybe light burn. What distance away from canopy.

With humidity running as high as 70% there is a chance that your soil isn't draining as well as it should and retaining water causing the roots to not get enough oxygen. I have no idea what you're using for soil but there's a possibility it is too dense. Even the new growth is showing signs of edge curling. As Fjeff mentioned, my first reaction was heat issues but at 74 degrees that can't be the case. I'm not a tent grower but maybe try pulling the lights back a little and see if it helps. Good luck

Looks to me like light stress and over watering. How close is your LED light? I have found that they need a little bit extra distance than what is considered "standard" to avoid heat issues.
