Arghh, browning on tips.

I asked questions about curling of edges and why are leaved thin, everybody said it's ok, but after a day , the tips of the first leaves have brown spots, on the plant overall doesn't look good.

What should I do?

Flush it with water. It looks like a classic case of overfertilizing

4 posts, words "classic case" And the fact i haven't used any nutes.
Seems legit.

Maybe it's from not enough nutes.. or water pH, I have no idea. I'd recommend picking up some good nutes like foxfarm, advanced nutrients, or general hydroponics. FoxFarm has a perfect feeding schedule right on the label of the bottle!

Hope you resolve your problem ASAP. Cheers!

I've see other people describe a "claw" look to their leaves and it's usually caused by a fan blowing hot or dry air onto the leaves. Heat stress can also cause it, but I doubt that's the cause in this case. From the color of your lights I'm guessing your using CFLs.

Hmm, i just looked and the tips are turning turning dark green, could say black but its dark green, It's not heat, it's not overnuting, fan is reaaaly slow, almost no effect on plant.
Only thing i could think is not enough nutes, but its so young.... 8 days. dafuq?
also,maybe water ph, but i dont have a meter.

Bump. Its dark dark green on one leaf, on the other, yellow, both tips lookm dry. Leaves are thin. Look kinda yellowish closer to tips.
It had a watering this morning. I think it was good then.
