Questions:Help..

using 600 watt mh+hps
used a 20-20-20 once.. i think i may have done it too early.. but they are about 6 weeks into seedlings... they have had quite a hard time so for these 3 to be up is pretty astounding..

any info would be greatly appreciated..
strands are white widow and cali skunk..

they dont look good

how old are they? id say try to hit em with superthrive, always helps get a stunted plant back on its way to new growth. no more nutes at the young age id suggest

wow, 20-20-20 is to strong for that.... ur talking about 20-20-20 for big veg plants with a super hydro setup with co2 setup...... i used co2 before with 20-20-20 once a week...wow that works real good..........just used plain water w/oxygen.

Hmmm, something is seriously wrong for 6 weeks worth of 600 watt light to produce those plants. Forget about nutes, something fundamental is out of place. The first suspect for slow growth would be excessive heat. Then you would need to look at the ph of your water and how often you water. But I might start with your growing medium. It looks like mulch. Are those wood chips in there? I also noticed that only the center of the pot is wet. When you water you want to pretty much flood the entire pot and let a lot run out the bottom. Then wait until it gets good and dry before you water again. I hope I don't sound too critical. I want to help but need more info.

What's your soil?
What's your low, high, and average temperatures?
What's the ph of your water and how do you test it?
How often do you water and how much do you use?

That should do it. Take care of those things and they should be out of excuses not to grow

right on thanks..

ok well..
regular organic potting soil, with 30% perlite mix..
temp. is around 74-79 degrees.
i test the ph of my water with a ph test kit.. always been at 5.8-6.0
at least water it 2 times a day.

That's your problem. You want to be watering once a day at most, probably every other day. The reason your plants are so small is because they are still trying to grow roots to fill up the pots. Letting the soil get dry when the plants are small does two things -> 1)The roots are stimulated to grow in search of water that remains only in the bottom of the pot as the top dries out and 2) contact with air is very important for roots, just like lungs they can drown when perpetually flooded with water. If they are being constantly overwatered, the roots will remain in a little ball and begin to rot. Pick up the pots a couple times per day. You will feel them get lighter and lighter as the soil dries out. When it feels like you're picking up an empty pot, soak the pot with A LOT of water. I flood my containers until there is standing water on top of the soil and plenty of water runs out the bottom of the pots. You want to thoroughly saturate every bit of soil in that pot. Repeat this process and your plants should improve immediately. All your other growing conditions sound right on. I know it's sometimes hard to trust advice on sites like these but look at my plants when they're five weeks old (don't mind the car exhaust parts in there). And I only use 400 watts. You can do the same thing. It's easy once you get a proper routine down. Just don't get discouraged and ask plenty of questions.

When it comes to seedling I usually feed with a really low does of big bloom in its first week approx five days after the three sets of true leaves form. Becareful with killing your babies with kindness of fertilizers. I typically only use vit B1 + hydrogen peroxide for watering schedules.
