Should I be worried about this?

My plant has a few leaves that are burning/curling at the middle and tips... only a few, and only on one of the lowest branches. It's 10 weeks old grown under a 400w MH. I've only watered with river water as I live on a wild and clean river. I've got it in a 4 gallon pot and I give it a quart of water almost every day.
Any help is greatly appreciated...thanks

Wow, I have never seen that before. I have no clue, the only thing I can say is that you shouldn't water everyday. Let her dry out a bit, 2-3 days before you water, or top of the soil is dry down to 1 knuckle deep.

I know... I don't intend to water everyday, but it does seem to be dry all the time.
Maybe I should stop the river water. The plant is otherwise healthy. Just trying to 'nip this thing in the bud", so to speak.
thanks

Start with testing your PH. Something is definitely wrong. If you do change to watering with tap water, just let it sit out for minimum of 24 hours. Most tap is fine to use and includes trace elements the plant needs.

thanks again...I removed the worst leaf...here's a better photo.
Why leave the water for 24 hours?

I wouldn't remove any leafs unless they are extremely yellow or damaged. You want to leave tap water sitting out so that the chlorine leechs out. Adding a air pump and air stone made for fish tanks will help this prosess.

thank you again for your help

No problem.

Have you run that strain before? That is strange indeed...

Sometimes certain strains will do funny things under stress like push out weird leaves.

Very true. The burning/ yellowing was more of what concerns me.

Thanks Doc...This is my 1st in about 15 years... no idea what strain...just found a seed and the inspiration.
I'll keep you posted if anything further develops.
