They look really good stop worrying so much its really nothing, I had many seedlings look way worse then that come out to be great plants. Just don't play with them very much and just let them go for a good 2 or 3 more weeks then give them some food with a high nitrogen ratio. When you start to see the bottom leaves turning to yellow and/or the whole plant become a pale color green then you know they need that nitrogen then start them on their feeding program. It is very easy to recover from nutrient deficiency, however it is much more difficult on the plants to recover from too much nutes - in a sense a plant never makes up for being over nuted because the damage that is done is in a sense permanent however they can do just fine and grow healthy from then on out if it corrected. especially nitrogen in veg so just be gentle with the food and let them show you when they are hungry with classic signs of nitrogen deficiency.
And for your question about your bagseed growing much better, this is very good intuition on your part you are a great observer...Feminized seeds tend to produce plants that are slightly lacking in vigor when compared to a plant that is is from a normal seed and this is especially noticeable in this early stage, not to worry though, if your plants are F1/F2 (which they are) they will still be amazing plants and you don't have to worry about males so much this way so it really is a toss up. I have come to the conclusion that it is better not to waste time and resource on male plants so when growing from seeds I like to go with feminized - still I am on the fence about this as its really not good for the cannabis species in a sense to use feminized seeds (from their POV). It is also just not a good idea to mess with bagseed because with bagseed you never know what your going to get even if you have 100 seeds from the same bud/bag half of them could be terrible genetics.
I will be following along your thread I am still learning a lot myself and hopefully I can learn some stuff from you and vice versa. Glad to see someone with such good observation and intuition growing and somone who really cares about their plants, you will do well.
