Looking for a little help

So finally got a small grow going.
Had a minor issue with hot soil when they were seedling's.
Couple good flushing's fixed that.
Been 12/12 for 11days now, and all the new growth at bud sites
is turning yellowish almost neon.
Soil is ffof, using ff big bloom starting 2day.
Under a 250 now the temp change is around 10degrees from day to night.
Was told 2 things either it was due to colder temps,
or it was a N issue.
So just seeing what yall think?

Are plant's infected with pest's?


it's very minor, but overall the plants look fantastic so I am betting it's just defieicnt and not locked out.

what water do you use on the plants? Distilled? bottled? tap? you change a water heater more recently?

Looks pretty good. I'd cut back on the N, the older fan leaves look too dark and a little over fertilized but the tips haven't burned so you should be fine as long as you cut back on the nitrogen.
