So, week 3 for most of these, and they're still pretty small. I had a thought that since I was using a new, bigger grow tent, and a new light entirely that I might be conservatively underexposing my plants to light. Previously they were about 4 feet away from the canopy and I changed them last night down to 2 feet and turned up the intensity to about 80% (this is what the manufacturers suggest). Almost 24 hours, and it seems like they are taking very well to the extra light. Hopefully will make a bunch of ground this week, as some of them are still super tiny for their age.
Not worried, I dont feel like this is unusual for me and once they really start taking off they'll take off.
