looks green to me.
Are you talking about the tips? Are you giving them heat in there or playing them music?
Whats your light cycle? Is there more than one plant in there? do you know your ph? Is your soil from oiudoors?
Is there white dots?
Cool temperatures in the grow room can cause color changes. 60F/15C temps and below will induce color changes.
i think i’d be a tad more concerned with whatever is clipping the tips off of some of those leaves.
Maybe that dark green and clawing comes from an excess of Nitrogen … 
The pink box. Is that an ozone generator? Maybe a heater?
The pink thing is a heater and I’m on flowering system from the VIVASON APP and the soil I got from a friend but I’m using super nova the make the buds bigger and I ha e them on an 18 hour lite cycle whatever I’m doing g wrong please let me know and it’s 3 plants in that one planter
Looking fresh and green!
Transplanting to a bigger pot before switching to flower will definitely help …
