What is the STRAIN? Where is it from, where is its home on the earth? Is it sativa, indica, both, auto?
In the summer, the moon is brighter, and as we go into winter, the moon is slightly less bright, but enough so that first of all switch to 20/4 for a while, and really, you can keep these still under the florescent for a while too, if you wanna use less power also. So turn up the light to 20/4 for starters until they fill out for their height.
Next, go ahead and keep them wetter than they are, they aren't wet enough, they don't need to be drenched, but after a week, that cup should be wilting and stuff, they aren't being kept wet enough. Don't let watering scare you, take all you can about watering, you'll see it's all the same: Keep it wet, but let it get dry between waterings. It's always moist and wet, you just let the top inch or so dry out (depending on pot size) - this is strictly to avoid mold and stuff with old water, the plants seem to like it too. And it's also for bigger established plants with root mass. At this young of age even if they have lots of roots starting, they should be kind of wetter than usual and it should be humid, april showers bring the sprouts and keep them wet and the rains make for humidity. Use a spray bottle and spray four or five or ten times depending how it sprays and just put like a new few drops of water at the bottom of their stalk a couple times a day. You aren't trying to water them again, they should be already watered and moister than you think you want - you're not spraying to water, you're spraying to soften the immediate area of the original planted area and humdify directly around the stalk and root base and all that, it'll promote more roots to shoot out from the root tip too it seems. it's okay to do the whole surface, and good to mist the plants a lot until they fill out too.
You can cut off the spraying when you see improvements.
It's hard to say though also what is the actual medium if I missed it? It looks kind of dense, one pic almost "polished" looking area - I hope it's not the medium stunting it. I can develop a bit more than that in those starter cups, quite a bit more actually.
And put the lights no more than 4 inches away from their very top. As close as you can at this point in time. 1 inch, 2 inch, very close - the flouro - to keep them the same height and let the stalks and foliage fill in more, trust me. Keep them wet, soil loose and aerated, short with light, fill them in, if you already transplanted, it's fine, just spray the area like you would otherwise be spraying the cup area.
Also, if you transplant right, you don't wait. I just uppotted a rootbound (bottom leaves told me - never before that signal in 8+ ounce container is it rootbound, and it will always coincide with the need for much more frequent watering - a high amount of roots all around, yellowing, is beyond rootbound) to a bigger pot <2 days ago and already have 4 bone-white root tips coming down to the different holes below my new pot. How? Transplant just before they need water. Dry enough to be careful not to crumble, but moist. Put a dry towel folded up (like 4 or 6 layers due to folding, so it's thick) under the pots after their after-transplant watering for 6 hours after most but not all after-water dripping and drainage is finished (example, I water in a sink, and when it is almost done, put the plants back, when transplanting, they go on a towel, when normal watering, they go on a dish. The towel gets warm and soaks down water and makes atmosphere for 6 hours, the plant shoots roots like crazy. You will be amazed). When you return to remove it, it should be damp, but not even moist. Do not leave it a whole day. Just 6 hours. remove it, and the next day, your roots will already be finding their way down, medium permitting. I recommend 15% perlite (or up to none at all) for starting seeds or containers smaller than 10oz, 50% minimum for anything bigger. In my case, added always to either happy frog organic or non-organic potting soil mix of any kind, even if it already has perlite, I will still add the bigger coarse shit.
I have learned a lot from this round. I had 2 rounds before. This one, I have learned so much new shit I had no idea about this stuff is super helpful backed by hands on. It's good info, I think you'll all benefit from this and like it real well.
