I would water until it is coming outa tha hole in the bottom. do this every 3-4 days or as needed.. As needed is when you cannot find any wet (darker) soil 2 -3 inches down!

Actually soil does have trace elements that will get the sprout to week 2-3. Its when it reaches 2-3 nodes that the need for ferts increase. IMHO
Small interuptions of light cycle WILL cause problems. Lights should always been on a schedule. if in veg. 24/0 is the safest. but if you have to give you ballast a break then use a timer.IMHO

WoW!!...interrupting the dark cycle is THE fastest way to turn your plants hermie. "IMHO"...messing w/ light cycles in ANY stage is risky, at best.
Seedlings "usually" wont require added nutes for about 2 weeks.
Did you read my post? Interruptions of the dark cycle in veg won't ever hurt your plants. In any way. You could flip the lights and nd off like a strobe and it wouldn't matter.
Grower paranoia over light contamination is in flower is silly enough, no need to send it off the deep end and freak out abut veg lighting as well.
24/0 is NOT necessarily a better light cycle for veg. That is purely your opinon. I have had equal success with hundreds of grows using one cycle or the other and have never been able to tell a difference.

..Did you read MY post?...you have an opinion.."I have mine". Do you see the IMHO in quotes?..that says it is "In My Honest Opinion"
"Interruptions of the dark cycle in veg won't ever hurt your plants. In any way. You could flip the lights and nd off like a strobe and it wouldn't matter."...
That is DEFINATELY "purely" your opinion, AND among the minority I would believe. MJ is a "photo-sensetive" plant. It's entire metabolism/life cycle is dependant on light. Spectrum, intesity and number of hours.
As mutt said.."Lights should always been on a schedule." ..ANY interruption in the dark cycle is "risky" at best. And that would be the opinion of the majority of experienced growers.
As for the 24/0 or 18/6, ect. vegging schedule. A subject that has been discussed, argued, debated hundreds of times with no solid conclusion. One side believes plants "need" a dark cycle, the other believes that they can metabolise as many hours of light as they recieve. Neither has been proven "better" to my knowledge.
BUT.... in my meager experiences, the 24/0 schedule has shown to be the most productive. Growing more nodes, closer together.

IMHO
The reason I said that 24/0 is the safest.
Is because there is no need for another timer. No need for adjustments. its just on. No extra cost.
With Compact florous. Most will NOT work with timers. Even says it on the box. Which most Newbs use for veg.
18/6 or 20/4 is good to give the ballast on a HID a cool-down period.
But I will not budge on my opinion that interuptions of light schedule is ok. In My Opinion it is not something that should be messed with. Find a schedule and stick with it. If the power goes out or something beyond the growers control is bound to happen. I haven't seen any - results. but not + ones either. Why take a risk by doing it on a regular basis. IMHO
On a last note. Flower period....that is not paranoi. Light leaks and light interuptions=Hermie. In My Experience. And documented over and over. Also the major downside to this is. If making crosses you may instill a hermie trait that won't show up until its offspring. Flowering is a very critical time in the plants life cycle. A lot of chemical changes are occuring during flower and should be respected as such.
