Are my plants okay week 3 veg?

I have been vegging for 3 weeks and my leaf’s have been cupping abit for around 2weeks of this they don’t feel dry and no spots but I’m starting to worry abit I have a couple thermometers around the tent they maintain around 26-28 with 50-60 humidity I have also raised the 400w hps
SORRY ABOUT PICSS

Whenever I see cupping 9 times out of 10 it's a watering issue in my opinion both will give similar results at the start I have seen over and under watered plants behave very alike sometimes usually if it was something to do with ph problems it should show you if there is a little bit of deficiency seeing as most rooting problems show different leaf issued. How often are you watering give me a little more info nutes, light height I know you already said your on 400w hps and also on that subject get the hps 400w out of the lamp because in veg a 400mh will do you alot more favours mate, so a little bit more info and we'll do the best we can so resolve it fingers crossed before it becomes something that can't be fixed

And decent setup by the way nice scrog setup looks tidy

Thanks also its fine now I sorted it hps was to close I was going on some bozo on utube

Ah happy days least it was a quick amd simple fix but if you go mh you will get tighter internodal spacing and less stretch because hps is in the farther red spectrum I learned from using both that I got a lot more vigorous growth with mh and a lot less stretch especially when flipping the 1-2 weeks is when you will get the stretch and mh can help lower that stretch best of luck bro

I'm going to say heat and light stress. They're canoeing and leaf edges turning upwards
