Why Are My Plants Like This

[MasterDsKush]

So my plants have been doing this for a while discoloring like yellowing and browning and many people said it was because I was burning my plants and using nutes to early but I started other plants with just distilled water and the same thing is happening I use Fox farm ocean forest for soil. My temp is stays from 60-75 degrees and humidity 45-55. I use a 400 watt mh with a cool tube and I have a grow tent with ventilation

They look perfectly healthy to me. I see the yellowing your talking about. But its not yellowing its just tender new leaves coming in. Thia usually happens to me when my plants are growing to fast, even for there danm selves. theres nothing wrong with it just means your gwtti g significant growth daily.
happy farmin;)
