I wanted to mist it with the fish emulsion/water that says WILL NOT BURN, but I think I should hold off on that for nowYes, hold off on that for now. Tiny little seedlings require very little in the way of nutrition/fertilizer. Unless your medium has absolutely NO nutrients (as in 100% perlite), it should supply what they need at this stage. And even with straight perlite, I have seen small plants live a long time with very minimal feedings (they just didn't grow a whole lot, lol).
I think more seedlings - and even established plants - get killed each year from "too much care" (IOW, an overzealous novice grower who feels that he/she ought to be doing something) than from neglect.
If you want to get something into the soil, put it in the soil - don't spray it onto seedlings' (few, small) leaves. But the only things that they need right now that your soil isn't likely to have... are water (when the soil has dried out enough) and light.
For the CFLs, I doubt it. Having your lights too far away will cause the stems to become too stretched (and weak) to support the plant, because they will be trying to stretch towards the light(s). For low-wattage ones, most folks try to keep them an inch or so away from the top of the leaves (and turned horizontally, so that they're actually sending more of their illumination towards those leaves than towards the walls, lol). With seedlings... You might allow an extra inch or so but, again, too much distance will leave you with spindly plants (that might just fall over).
Do remember, however, that CFL bulbs still produce heat (and, watt for watt, quite a lot of it, lol). You should place an oscillating fan so that it can blow across your seedlings. This will serve two purposes - it helps keep the bulbs from overheating the plants, and it will help your plants/stems become stronger. At this stage, a gentle breeze is better than a hurricane - you don't want them to be pushed flat, merely to "move" in the air. So don't use the highest setting on the fan, and don't place it an inch away.
I have no clue as to the LED. My guess is that it's a low-power / low-intensity one, but that's just a guess.
Unless you are planning on growing them outdoors and are, therefore, "hardening them off" to the outdoor conditions, I would not bother. It's a good way to unintentionally transport pests into your indoor garden space - and spider mites (et cetera) are a real b!tch to deal with.
I have a feeling that I will be asking my last question... seconds before I die.
When is good to top a plant? Some folks would say, "Never," lol. It really depends on what you are trying to accomplish by topping it (and the strain). At this point, your plants can use all the leaves that they have, IMHO. As the plant grows larger, you might consider a less drastic form of training - tying the plant's uppermost growing tip down so that it is no longer the uppermost growing tip will cause the plant to redistribute its auxins ("plant hormones"), which will promote branching. Read up on things such as "low stress training" and "scrog" to learn more. If you only want a certain number of main branches, though, topping the plant can be useful for that.
Yeah the plant is bigger now, I have only fed it one or 2 half strength "feeds" right now. Bottom leaves were yellowing slightly, was trying to figure out if it was due to ovwmerwatering, n deficiency, or needing a transplant. A friend keeps asking when am I going to top it and I didn't know what to do... so many different optiins. Then supercropping was brought up. My guess is that it's about 3 weeks old (plus or minus?) I got a little floralicious plus for cheap under 10 bucks, and I have ewc, king syrup, sns root/veg booster (kelp, humic acid - may be similar to FPlus), and fish fertilizer I was thinking of trying to brew tea and put all of it in... anything I should keep out of the tea? My first one I think I will do on the weaker side...
