Tiny plants dying - twisting yellow/dying leaves - high pH? (PICS)

For the first one, I poured some hydrogen peroxide on it a few hours ago.. no real change?

The rest are getting worse, fast..

This began with one plant, but after watering, the rest started showing symptoms. No nutes, miracle gro soil - but it's from houseplants.. which had manure in them months back.

I'm thinking high pH from hard water.. so on two plants, I watered with some lemon water

dude let me tell your right now...if you want good plants you have to get a ph test kit and you have to ph your water to the right ph. otherwise lol

Are you sure you don't have ferts in your soil? I've never use a ph test kit but i've never had a problem with ph either so I can't help you with that one.

I might.. there's composted manure in the soil, but that's months old.. I figured that would have been broken down and leached by now? Maybe not

Anyway, assuming it's fert burn, should I flush the plants?

Since I have to wait for awhile for chlorine to evaporate from my tap water, should I flush with distilled water?

How exactly do you flush? Just saturate with water over and over?

What kind of Miracle Grow are you using? Depending on its type it may have time-release nutrients and if that is they case they may be what is burning your seedlings. If this is the case, your best option would be to transplant in non fert soil until they are old enough to handle ferts.

PH problem.

I agree with the above.
Always use seedling soil.
Some strains hate nutes especially when they are young

they look OVER watered

Stop everything and water the roots out into new soil. Get some black earthworm soil and quit playing scientist. Mix with that Styrofoam so the soil lets the water through slowly. Water every three days only if needed. Get the ait in there. Raise the lamps a bit.

when u add peroxide you might want to mix like 1tsp or a cap full with 1 gallon of water and give it to them that way(not the whole gallon of course though just a small amount).
