Hey guys, hope you’re all well. Just looking for a bit of a diagnosis if possible. I’m growing one plant in a small, stealth box, set up. 4 weeks in and my top, new growth,leaves started turning a bit yellow. I’m thinking it’s light burn as the tops got a little close to the light. Do you guys think this is light burn, or the start of something more sinister? Any help would be appreciated.
Light burn.

How close were they to light ?
and kind of light .
and kind of light .
Literally about 4 inches away. It’s a 100watt led, but I’ve got it dimmed down to 30%. I moved the dimmer up on the Friday to about 30% and started noticing the fade on the Sunday night. So that’s why I was thinking light burn.
This is what the plant looked like on Thursday before I turned the power up. I’ve bent the plant in the previous pictures, to get it at a lower level, and away from the light. Some guy said iron deficiency, but I really can’t see it being that.

Hey there dude. So my cabinet is only 40cm wide, 50cm deep and 74cm high. It needed to be small because of people coming over to visit. So just a small stealth cabinet for personal use. I’m using 100watt led with Samsung diodes. It was dimmed to 20% but on the Friday I turned it up to about 30-35% and then noticed this yellowing on the Sunday. I’m using soil. Peat with perlite, plus added chicken shit pellets, worm castings and a bit of compost. Soil ph 6.2. I’m just feeding worm tea, and used some aloe Vera blended up and powdered barley a few time so far, over the course of this grow. Everything has been brilliant up until this weekend when I noticed the yellowing on Sunday. I don’t think it could be iron as my soil ph is not high, and there’s plenty of nutrients available to the plant. I will pay a picture of the plant on the Thursday, because I turned the dimmer up. Thanks for your reply man.
