Yellow mottling on leaves

Hi guys, first time grower here, I have very little knowledge as of yet and have come across this yellow mottling on some of my leaves. I have taken some off but it keeps happening to others. I don’t want to keep pulling them off, I’m worried I’ll end up with none left haha. 

Any ideas on what it is, what’s causing it and how I can fix the problem?

Thanks in advance

It would be useful if you could upload some pictures for everyone to see and if your plant is in veg or flowering state.

I'm not sure how to upload a picture on here but I'll have another look. They're in veg, grown from seed about 2 months ago. Temps are higher than I want them, anywhere between 30 and 34 degrees Celsius. Growing in soil, 600w hps

From that one picture it looks very similar to nute burn, are you feeding it any nutrients at the minute? If not it could be N deficiency

I assume you're growing in a tent?

You say you're growing in soil, what type is it? I have seen that some soil won't have enough nutrients in it during veg state, so it could be a deficiency

I would hazard a guess that your temps aren’t doing you any favours.. could be causing you issues with your roots.

 

too hot or too cold and your plant won’t be able to take up nutrients. Very warm temps plus water causes organic material to break down (which is why compost heaps are warm and wet).. 

 

just my guess - i could be wrong.. i can’t see any pictures.

 

 

edit: i found your photo.. that looks like a hungry leaf, which would suggest the nutes aren’t being used fully. Are you able to dim the light to 400w during this warm spell?
