Sounds like you have everything started well, I would just add that seedlings do not need any nutes. While your plants look tall, they are not mature enough for the nutes yet IMO. That length I think is stretch because you are using an HPS right now, causes more stretching. I would flush them out w/ RO WATER, no nutes, I do add some calmag and 1 drop/gallon of SuperThrive, but you don't even need that. Be sure that everything that goes in is ph'd to 6.5-6.8 whatever you like. And be sure that it is runoff at about the same. It doesn't have to be exact. When I do add calmag, it's usually just 1 or 2 ml/gallon, but it is not necessary by any means, and I would keep it simple and just not add it to start.
Starting them in small containers is the way to go, much easier to control and correct issues if you have them. For instance, just one of those cups, to flush, flush w/ 3 full cups of the same size and bang done. To be honest, you may not even need to mess w/ flushing, but just back off the nutes for now. Be sure that you are watering w/ ph correct RO WATER, and continue to do so until they mature a little more. Don't mistake the size for a sign of maturity. You shouldn't need to water w/ nutes until they are re-potted I am guessing.
Take all this w/ a grain of salt, just my experience, I have done very similar things to what you are doing now. You are headed down the right road. Keep it simple! Read, alot, this is a great place to learn, lots of smart folks here.:jointsmile:
I didnt think they're seedlings anymore, are they? They're growing new shoots like mad, and are over half a foot tall, and about three weeks old. Repotting is going to happen soon, the roots are beginning to find their way out of the drainage holes. As for RO, unfortunately I dont have access to RO water ;/. Distilled is the best it gets for me.
