Do they looks healthy?

They don't look healthy, I'm afraid. I don't know about the red colouring. But what I do know is they look heavily over Watered, do you have a working extraction fan? How often are you watering? A container like that probably wants watering no more than every 3-5 days. Are you checking your in and out ph?

If they have a pink, orange, or red hue then it is most likely a molybdenum deficiency. ^Molybdenum is a micro nutrient that can get locked out with to low of PH. ^Dont cut any leaves, your plant is having some nutrient issues right now amd doing so may induce more shock. ^In soil, molybdenum is best absorbed by the roots in the 6.0 – 7.0 pH range (some growers recommend avoiding a soil pH of lower than 6.5 if you suspect a molybdenum ^I would suggest to check your PH and flush with nutrients that contain Molybdenum. ^A great resource I found with diagnosing info, pictures, and fixes is the below. https://www.growweedeasy.com/cannabis-symptoms-pictures Great Luck & Happy Growing🌱

They look like they maybe slightly light burned? Maybe even nutrient burn? I’m not exactly sure but something does seem a little off.
