I’ve just notice this, I’m assuming it’s happened fairly quickly.. it is only happening to one of the plants that I can see.. could it be light burn? It’s funny because it’s definitely not the tallest plant in there..

You’ll need to give grow details like light strength height, nutes , watering media , ph etc. We’ll be guessing just like you with a picture.

Have 17 clones, that are about 2.5-3 weeks old. Under two 600w lights. They are all in Coco Cana. My res sits at 5.8-ph, runoff is sitting at around 5.7.. I’ve just started feeding at a 25% run off but that’s only the past two days. Before that I wasn’t giving a run off and would let them dry out before I fed again.. learnt this was wrong so have corrected. I feed every day. They are stilling roughly 400-500mm away depending on plant height in there. It’s just strange it only seems to be one plant.. for now anyway. I did have yellowing tips but that was on another thread.

As stated above total guess. Your feed strength is to strong or soil to hot

hmm I’m definitely feeding nutes within their recommended range.. as for too wet. It’s my understanding from a previous post and numerous replies that you pretty much can’t get coco too wet? I fed again when they were 90%ish

I would say you can't get it to wet, but you shouldn't keep it soaked. You can't get rockwool to wet either, but you shouldn't keep it saturated all the time. Meaning water, let it get down to 33% of its wet weight and water again. Don't let it dry but don't leave it soaked.
 
Not a coco or clone guy but it might be some root issues from the way you were drying it out . See if it doesn’t turn around now that your feeding and not drying it out. Better help is coming lol i probably wouldn’t have 600w on them yet either if your at 100%

Haha. Sweet! I think I’ll see what the next day or two brings and go from there, something definitely isn’t happy so just thought I’d pick a brain or two and see. Yeah, there is 2x 600 watt in there at the moment. When you said if you’re at 100%?

Yeah that makes sense, I definitely haven’t had them saturated before watering again.
