Soil looks dry. What's the humidity? To low? What's the temp? To high? I'd start there. What light? To much power to soon? To close to the plant?

Humidity is 45-60
It's been pretty warm lately temp got up to 85 and gets down to 64 at night.

I thought it might of been to close but once I raised the light the leaves started reaching

THAT SOIL IS DRY! It looks like you started those seeds in something. I'm not sure what it is. But if it's one of those pucks that expand when soaked in water I haven't heard good things about them.

To be honest I don't like solo cups either. Young like that you don't want to confine the roots. They can fill that cup in a week. Personally I go from flats seedlings or cutting to 1 gallon pots. Then to 5 gallons. More roots the better the plant.

Yea I actually just took a look at the roots and noticed it started to circle. I'm thinks my of transplanting to 1 gallon tommrow.
So what do you think the problem with the tips could be from underwatering ?

Oh and it's a rapid rooter

yeah with the mesh? I'd ask around but like I said I haven't heard a good thing about them. My guess it's a combo thing. Tight roots - to long between watering - high temps. Water ASAP transplant ASAP make sure temps stay below 80 76/78 is ideal. What about circulation and ventilation. If it's not getting enough fresh air it chokes the plant and makes it even harder on the plant to combat the other issues.

The truth is many people make it harder than it needs to be.

Those are not peat pucks it is a rapid rooter and there is no mesh around it. I've been using them for over 10 years with excellent results.
