Stunted seedling growth

So I have two blue thunder seedlings going on week 3 today since they sprouted and they only have 2 full node sets and are barely 3 inches in height. Is this relatively slow growth? How fast is normal average growth? Also some leaves are curling underneath eachother, I was reading it could be cal mag deficiency? My ph is 6.3 in coco coir perlite pre mix. I’m using viperspectra 450 w led 36” above tops in a 2x2x4 tent.

Your pH is too high........should be around 5.8 - 6.0.
Based on your other 2 threads.........you need to start feeding daily to run off.

They look a little behind but not terribly so. Should improve greatly with bringing that light down. I got some about a week ahead of you and they are only a little bigger. Run mine in soil at a range of 6-6.3 too...coco I have read is good in 5.5-6.5 so you should be ok there. Just give it time

Here is an update a week into flowering they are very happy. The one on the left is bluethunder( from seed) and on the right is pemmex which was a clone. I had tossed the deformed one because I ran out of light coverage space. When/should I remove more smaller bud sights. I just don’t want a whole bunch of popcorn and would rather the plant put energy in the healthiest sites!
