Hey Jelinda, I don't have a "link" but I can tell you I've been growing using lights for 2 years, and the plants "catch up" as soon as the weather warms up enough for me to put them back outdoors
I live in Seattle so that's usually in late March, I place them outside in full sun where they're happiest and they do amazing things, and then I bring them in (usually early Oct) and they just "survive" - so I'd say, Don't worry, they look fine, that is new growth at the base of your plants and it looks great! Often the plants are reacting to what you've given them a couple of weeks before (so when they were in full sun outside in the warmth)
The other thing I've found with my plants is that when its colder, water them less, I water on a schedule of once per week, and when they're indoors I water the same schedule but much less water at a time - so outdoors I poor the water on until it flows out the bottom, indoors, in the colder temp, I only use enough to cover the surface and that's it...I'm used to philadendron's and ferns which love lots of water so its tricky for me to water so much less, but the plants respond. OK, just my 2 cents, I hope this helps, I'll put some photos up of my plants soon
Enjoy!
