hydro mystery with pics

These are my babies 2 of them look good but the others dont. i dont get it. i posted another thread but got no responce, if you scroll down abit you will see my write up. the title is (hydro prob cont). I also have 4 in dirt doin the same thing. it is a old strain 10 yrs + could it be a dead or dien strain? The last pic is the one in dirt next to the others i just moved into the bud room. they do fine till week 3-4 then they start to yellow as well

looks like a nutrient problem to me

i would replace your tank water with straight pH balanced water no nutes.
let it sit for 24 hours in the clean water. then change it again with your pH balanced nute water. maybe back off the nutes a bit.
if that doesnt solve it then its gotta be a heat problem
