Unknown problem... sprouts

Hey guys, my sprouts just will not survive! I have no idea what I am doing wrong. The first week I had overwatered them and this is what they looked like.



I quickly changed my watering. Now I water whenever the soil is relatively dry (3-4 days between waterings). It has been a week and a half since then and the sprouts are constantly getting worse which leads me to think watering isnt the only problem.

My soil mix is 3 cups potting soil to 2 cups perlite.
I have not added any nutes.
The pH of my soil is between 6.5-7.
I have been adding 1 tablespoon of 3% H2O2 per gallon of water.
The temperature of the room is 78-83F

This is what they look like now. As you can see they have stunted growth too.




I have given up on these sprouts and am in the process of germinating new seeds. I want to see if yall know what the problem is so I dont repeat it on the new set of seeds. This is my second grow and I never had this problem my first time. Thanks for your time!

Any ideas? Could it be possible for soil to not have any nutrients from the start?

what type of lighting are you using.

I have a 400 watt MH. I'm keeping it 2'6" from the sprouts so the light isnt too intense.

STOP USING H2O2!!!

peroxide kills the beneficial bacteria that have a symbiotic relation ship with the roots. no bacteria, no feed.

imo, transplant, knock the dirt away, gently place them in new homes, and use superthrive if you have it.

no peroxide!!!

Man those are some yellow plants, hopefully some one else chimes in.. They looked a little stretched and over-watered. But I have never seen such yellow seedlings. Nutes don't matter much the first couple weeks, the plant survives on the 2 little circular leaves which eventually fall off after a couple weeks.

Well there you go, I was going to say something about the H2O2 since I have never heard of it being used, and everything else your doing seems spot on. So try to stop using that.

def. ditch the H202...

i use it to kill things in the soil... cuz thats what it does...

yes, do get some superthrive, and if you have a hydro store around, some kind of KELP product will really help bring them back to life...

a little innoculation of some mycorrizhae bacteria, humic and fulvic acids will really help getting that little micro heard back into action....

Thanks for the replies guys. I was under the impression that H2O2 helped keep the plants oxygenated and prevent rootrot. Could H2O2 really be causing this much damage? I will take your advice tho and will stop using it since I'm sure you know more than I do. I'm just going to let these sprouts die since I already have new seeds germinating as we speak. I dont want all this stress affecting my overall yield.

Also what is the purpose of superthrive? I will be making a trip to the nursery to pick up a few things and I will purchase this if it is beneficial.

Plants like CO2.

superthrives full of vitamins and minerals and hormones i think that really helps things along... =]

and at 1 drop/gallon... lasts forever

Sounds good. A few more questions about superthrive.

Should I feed it superthrive every watering?
Should I add superthrive even while I am giving it nutes?
Should I feed superthrive to fresh sprouts or wait till the 5th node like nutes?

yes
yes
yes

superthrive always.... until week 2-4 of flower.

i cut it out during the last 2-3 weeks, but why should we stop sooner? just curious...

hormones for root growth seem to take away from flowering. i did a side by side, st really boosts them in the stretch period, but seems to slow things down after that. after the stretch, i nix the st, and concentrate on food.

huh... good to know
