First 2x2x4 grow tent

I bought this seedling from Cali Kosher(Empire Wellness). Seedling only about 3” high and the roots was about to pop out of the pod it was in. I let new growth start to form and allowed time for the plant to adjust to the new home it was going to be in. After a week or so I went ahead and transplanted into the final 5 gallon mesh pot. It has been almost 2 weeks now since I started and I haven’t seen any major issues. I do notice the stems on some are starting to turn purple( not sure if this is a issue I’ll need to read into it more). I have my 1200w dimmable light set to 700 during veg and plan on boosting it throughout the grow. Applying small amounts of feed over the tooted area and my feeding schedule is a water water feed scheduled to help ease the nutes into it. Any advice would be much appreciated. Thanks and happy growing!
