Hoping someone can identify this problem..Here's lowdown with pics..

Alright guys and gals, here's the lowdown:

3 week old seedlings.
Constant 24/7 light cycle,.. CFL's ( 10, 26w 6500k) about 6 inches above plants.
Started in peat pellets, then red solo cups, and last Saturday to the 6" pots.
PH is about 6.8.
Started trace amounts of Fox Farm Grow Big last week. 1/4 teaspoon to gallon water
Using tap water that I distill first. roughly every 3/4 days I water.
Soil is: 50% MG potting mix, 25% MG Perlite, and 25% Worm Castings
New 6" pot has small gravel in bottom for better drainage
Temps are around 72-75f
Noticed a couple fungus gnats yesterday, so I got Fox Farm "Don't Bug Me", Neem Oil, and the bright yellow sticky paper gnat traps. so far caught 2 gnats..I think thats all. Caught them before they spread..( I hope). I have not used either FF or neem oil, just the stickys so far..But wanted to have them just in case. I may have left things out which I will answer, being I'm asked..
Seedlings will go to 400 MH tonight..(first dark time tonight, for 6 hours) and then 400HPS for flowering...

The thing is the center veins are becoming yellow, and one of the leaves is crumbling away on the edges. Plants still look very healthy, and have grown amazingly fast.. any vets out there wanna chime in?

Ya Fox Farms is a little hot especially Grow Big and Tiger Bloom. My answer would be too many nutrients man start off with an 1/8 teaspoon instead. Your plants are under some stress and that would be why they are so droopy, over fertilizing and recent transplant will do that. Just chill off of them and make sure u are watching the PH of the water u feed them with. It needs to be 6.3-6.8 for optimum nute absorbtion. Your MG Soil already has nutes in it, probabley enough for 5-6 weeks. Flushing should be last on your mind but only if the problem becomes much worse. Hope this helps, Good Luck!

Oh and by the way try looking into the Fox Farms line of soil, smokes your MG guaranteed

Thanks kindly man, I didnt realize such a small amount was so powerful!...(Grow Big)...Since no one else has chimed in, must not be too much a problem yet.. I will definitely take your advice...I hope they like the new 400 MH in a couple hours....

Oh they will! just make sure you do the "hand test". Place your 400 watter 12 inches from your girls and place your hand knuckles up the same height as your girls. If it doesn't make your hand feel uncomfortable then move those lights closer. Just be aware about how much your girls grow a day and adjust your lights from there. Keep your Cfl's or at least some you will thank me when your plant is three foot and your getting enough light to the lower branches. First thing just a couple make a huge difference especially in the late flowering stage. Might have to accomodate for the heat you will be producing so search for a good fan or a couple smaller fans. Second lets say all your plants are girls, u think a 400watt MH or HPS is gonna grow u fat nugs, every plant? What I'm saying is keep your CFL's and maybe invest in a nice reflector.

Yeah, I have all that.. good air in, good out, in a 4' x 2' x 4' tall tent. good reflector with 86 degree temps (with MH bulb) probably come down a degree or 2 with the HPS.. underneath that setup is a 1/3rd sized cube I built with all the CFL's just for seedlings. tonights the night!!! MH should kick on in a few minutes!! SO excited!! Hope my girls are too!!!! Thinking hard on the scrog idea...seems simple enough.....

The two fertilizers mentioned are not organic. The big bloom is nothing don't even worry bout that plus it' the only one that' truely organic. I use BB and happy frog only. Haven't used the other 2 becaue of chems. I don't see anything really wrong with your plant at this point , pic 4 looks like it's beginning to wilt i all. I think the leaf burn may be froma leaf sitting in soil(after you water...happens to me all the time) new growth is fine.

6 inches is a long way away.

Normally I would agree, but under the conditions that they were growing excellent,..I felt comfortable. the last week or so, they have been around 3" from tops to lights

cut back on nitrogen they are too green and are over fert.
