Shagreg Looks overwatered to me. Id let it dry out more between watering - every 2 days for a plant that small is likely too much. Once it is bigger and has more roots it will need more frequent watering. Other suggestions: Change light to 18/6 and when starting nutes don’t do more than 1/2 strength every other watering to start.

Phatboy007 Thanks for the suggestion. I’ll wait till the soil gets dry then water it. I’ll keep updating it. Any reason why the yellowing is there ?

Shagreg Not sure, but it looks like nutrient deficiency of some kind. Does the medium have any nutrients in it? If not you may want to add them with your next feeding.
