Help save my plants from imminent death! +rep

My plants are on the brink of death.

Heres the story: I germed in jiffy cubes and transplanted to a soilless organic media consisting of compost, coco coir, perlite, and some lime. The soil is pHed right around 7 (according to my dinky analog pH reader). I think I overwatered and ferted a bit early with a 5-2-5 organic supplement, but since then I flushed the plants and cut back on the watering - they never got better so I transplanted a few days later...still declining. They will die soon - please take a look and give some advice. +rep for those who really help.

My thoughts:
I dont feel like its a nute def because the yellowing started so early. There may have been some early heat stress but temps havent been over 83 in the past 2-3 weeks.

Thanks

Are the leaf tips curling?? they look to be curling up? i would take a look at the Nutrient Deficiency charts, but its looking like its a Mg deficiency to me..

N what's rep? Most people post to help, not looking for credit here

this happened to me and i was able to save my plant. have no idea why or how it happened but I flushed my plant with a ton of water and made sure it had good drainage to dry out. then once it was ready to be watered again i used Alaskan fish food 5-1-1 nutrients (get at lowes) and just watered the plant when needed and it survived and is flowering nicely now.

Simple. You fertilized too early. NO FERTILIZERS AT ALL IN ANY MANNER WHATSOEVER FOR THE FIRST 2 WEEKS MINIMUM.

Just use water with just a touch of molasses and hydrogen peroxide now.

Might work.

the ph is a little high but within range
i agree - flush well, don't feed until they recover
i think they just stressed with heat and nute burn

Thanks for the advice guys - I already flushed once and transplanted since then. I have not added any nutes to the transplanted soil so I dont need to flush again right? Also, how much H2O2 should I use? Ive heard that too much will kill of the microflora around the roots that are very helpful in organic grows.

So I think what Im going to try is molasses + H2O2 + light dose of cal/mag and try to make sure Im not overwatering - does this sound like a good remedy?

try a couple of capfuls of h2o2 per 1/2 gallon water.

So it took me quite a while to rehab these plants but it worked.

Changes:
1) Moved from soil to DWC bubbler
2) Bought a NICE digital ph/ppm meter
3) Learned an appropriate nutrient schedule (Blue Mountain Organics)

It like night and day...check out the pics

The first is Day 1 (ie. day I moved the plants from soil to DWC), the second pic is 7 days into the DWC, and the third pic is Day 15 into the DWC.

nice comeback zorro , they really took a beating in the beginning and with enough tlc you brought them back. Its always nice when u see ur babies pull through. Its hard but in the beginning i never nute until the 4th set of leaves .Seedlings have everything they need up to that point. Good luck with ur grow it looks like u got it under control.

Thanks man, this is my first grow so like a typical newbie I jumped the gun with them and started ferting too early. I also think it was that combined with overwatering, transplant stress, and heat stress in a short period of time that almost killed them. They were forgiving though
