Ahh... okay. Well, seems it MIGHT be a P deficiency, but can't be sure. I was hoping I wouldn't get deficiencies so shortly. Plus, only one plant has red stem, one has partially red stem and the rest are nice and green. And they all have the same bought soil. So, here's the questionaire...
The all-red stem (Firstborn) is about 10cm tall, partially red stem (Dudess #1) about 6cm.
Light shines mostly from the side of the closet (see pic). The two plants I mentioned are those in the back row. The closer one to the light, FB, may be 15cm away. D1 may be about 25cm. I recently lifted the lights from the back of the closet to the side. It has its back against the only brown wall now, so I hope the white ones help reflect the light a little. Here's a pic of the old days, before I moved it.

They're nine days old.
They're Chronic.
Started them from seed.
They're in clay pots, which means no holes in the bottom. Can't drill them, either. But since they're clay, they should be porous enough to use during the veg period? During the first replant, I'm planning to get plastic pots with holes. They're about 600cm3 (no hablo en gallones), roughly. At least that's how much is covered in dirt.
They grow in dirt.
It's flower soil. Its name is Jokakodin.
It consists of 40% dirt, 10% sand and 50% peat.
conductivity: 35mS/m
pH: 6
main nutrients: N 55mg/l, P 20mg/l, K 70mg/l
granulas not over 50mm (seems a little much)
harmful heavymetals: Cd, Hg, Pb not over the allowed limit of 46/94
I haven't added anything to the soil yet.
Lights are fluorescent, 2x3350 lumens. If I weren't broke, I'd get an extra that shines right on top of them... and some soil measure tools.
Master TL-D, Super 80, 36W/830, 2mg mercury, lead free, 3350lm (lumens). Two such tubes for one lamp. All I know. The bulbs seem about
I'd say about 4 ft seems right.
No ventilation. But, since they're in a closet that has a few holes and a door that's not entirely shut; and since I open the door a few times every day, they do get air. I'm afraid there aren't enough lights to overheat them.
No specific LST. But the FB plant was closest to the light, so it stretched itself to one side, pretty bad. I supported it a little and turned the light to the other side, so it won't grow entirely sideways. You can see the curve.
And, finally (but before the pics), a link to my grow journal.
