Is my plant sick?

Hi all. Thanks in advance for any help or advice. This is my first grow and am only growing one plant to see how it goes. The tips on my plants are beginning to turn yellow. I have them in soil with miracle grow nutrients pre mixed (yes I know). I haven't added any nutes, only water. I have 2 60 watt led lights in a fairly small box. I don't think the temp is the problem as it never gets hot in the box. I've read a lot but get a lot of conflicting info. I would assume it's either a ph or the pre mixed nutes. Would appreciate any opinions as to if my plant looks really sick.

Doesn't look all that bad to me, the soil seems to be a little hot, but just let her grow out a bit and get used to the conditions. Don't go doin a bunch of crazy shit to adjust the pH. Is your soil organic? Does that container have holes in the bottom for drainage?

I wouldn't be losing any sleep over it.

Thanks for the responses. I don't believe the soil is organic. I basically used what I had. It's miracle grow moisture control potting mix. I have several holes along the bottom. There's plenty of holes for drainage and oxygen. I was recently reading that you generally want to stay away from miracle grow and also feeding plants nutes too soon. Was hoping that since I did both (lol) it wouldn't end up killing her in the end. But ya for now I'm gonna just keep watering the same as I have been. It's my first grow so I'm not really expecting much but I'd be nice to smoke some good kush that I grew myself. : )

Throw a little cal/mag in there not a lot but just a little. Its the only thing that it looks defeicient in to me. Get a sol pH tester its cheap enough.

nice looking little plant! let it grow. it doesn't need to be fucked with at that young age. GL

Looks like early stages of nute burn. The plant will get use to the nutrient levels as it grows, it may or may not get severally stunted and just stop growing or it may continue to grow normally.

GL with your grow!

You have one or the other, I would check if your light is too close causing light intensity burn, if it's not this than the soil has too much fertilizer in it which I highly doubt. You shouldn't be adding any fertilizer at this stage since their so small and there are already fertilizers in that mix.
