.

One problem may be the heat. Are you venting the tent exhaust to a different room or just outside the tent?

What are you feeding them? How often? Are you soaking your pots til runoff?

More questions to come.

It's not heat. It was 117 at my house today (it was mid 90s in my grow) and my plants don't look like that. Look for bugs look for things moving in the soil too. What are you growing them in (substrate) and what are you feeding?

Hmmm. Honestly it looks like a pH or nutrient thing turning it yellow. Is it worse at the bottom like the pic's suggest? Light burn is worse at the top as that's what's closest to the light. What's your pH? What kind of soil? Are you feeding nutrients?
I also agree to watch for bugs. The little spots look pretty close to what my grow did the time I got thwips. Could be micronutrient related but from what I see I'm leaning more like bugs.

It seems to be most down the bottom I think. I keep them about 18-20inch from the light I got them gifted all I know about the soil is it’s ment for tomatoes just a basic soil. They are getting 1ml biobizz root juice to 1liter of water. But I have got thrips iv gave them a weak neem oil spray and iv ordered ladybugs lol but I was told they wouldn’t damage the plant too much

I do have thrips in my tent but my friend told me they wouldn’t do much damage

Try getting rid of them if you can, it may cause confusion if youget something else wrong with it. kinda looks like spider mite damage to the untrained eye.

I used to grow with a cousin who had access to free grow bags and insisted on using them. For 12 months we battled every bug, mould, nute and ph problem I’ve heard of.
We parted ways and I haven’t used a grow bag since and never had any problems I haven’t caused myself.
Tomato soil is the devils spawn. I hate it.

Good luck mate, with plenty of care you can still pull monster nuggets from those plants and I’m sure you’ll regain control.
