How big are those pots? Possibly root bound?
 
3 gallon it’s only been grown for a month I wouldn’t say it’s root bound yet I was thinking it was a magnesium deficiency but then also think it might be a problem with my PH pen or the soil being too hot I have no idea where to starts it’s taking over my biggest fan leaves right now prolly a totall of 6 leaves the bottom leaves have stopped taking in damage and seems to be on the bigger level I ones now I have no idea what to do or where to start like I said

I’m thinking magnesium as well if it’s affecting the younger leaves now. After about a month in fox farm soil I’ve noticed is when my plants start to get hungry. I feed organic dry amendments and my plants seem to respond well but it’s slow released meaning it is not readily available to the root system. You could also look into brewing a compost tea. Try not to panic too much based on the pictures it does not look horrible. You have time to correct this
