First grow, need a little diagnosis

[Promise]

Good morning guys, thanks for letting me be a part of this awesome group.
So my setup is a 4x2x72 grow tent with 1000w viparspec light.
5 gal pots with promix hp with mycorizae mixed with extra perlite
Light are sat 24" from the seedlings
No nutes as yet

I have a couple pictures of the plant just need to know what's happening to the plant and how to fix it
One is a purple urkel and the other is a cheese.

They seem more than 2 weeks along...looks like they need nutrients.

 

[Promise]

Around 3 weeks growth so far

 

[Blew Hiller]

ProMix has nothing for them...they are starving.

 

[Jack420]

Yeah give them a light feeding

 

[Promise]

Awesome, thank you.
I was told dont feed until the embryo leaves fall off, will get some feed into them today, thank you so much

 

[Jack420]

Wrong all depends wat soil u in most soils are good for a few weeks but pro mix don’t have nothing in it it’s like a soiless medium but feed n there will blow up

"Yeah give them a light feeding "

Agreed. A top down watering with a liquid fertilizer. But............mix it up at 1/4 strength. Best to apply less, but more often and ease them into a higher nute environment over a couple of weeks. Avoid burning them and will recover nicely i reckon.

Added nutes to the soil, ph of the water is at 5.9 1/4 measure of the ferts i have for my aquarium plants and the growth has exploded

 

[Promise]

Thanks for everyone's help
Much appreciated

Anyone know what this could be?
Plant is 2 weeks into ththe veg stage
Looked through my plant deficiency lists and nothing shows like this

Hi. Just reading through. You look like your leaves had some problems since the start. I’m wondering if this might be your light. When its too strong it bleaches the leaves. Your new growth is taking the brunt of it, which makes sense. I would have started it at 3 feet or more and lowered it gradually. Does your light have a veg and bloom switch. It should be on veg only.

Hey Calvados
No just a single power on switch, and the light is around 36" away from the plants on an 18x6 light schedule.
These are autoflowers too so the veg/bloom isnt needed for the plants or so I have read (I am probably wrong)
I found an "iron deficiency" diagnosis sheet that looks and sound remarkably similar to what my plant is going through, its funny it's only this plant because my Cheese xxl in the same tent under the same light is doing remarkably well.
I'm going to flush it tonight with some fresh 6.5ph water and see what she does in a week and then add some calmag and florets nutes and go from there
If it doesnt clear up a bit in that week I'll cull the plant.
I like learning and researching things so it might also become my experiment plant

 

[Calvados]

I don't use promix, but I thought PH was meant to be around 5.8.

You are using nutrients for aquarium plants? Complex salts, ppm dosing? Or is it bottled? What is the NPK on it? What brand , if there is one?
You should make sure it is safe for edibles not ornamentals.

 

[Promise]

Using general hydroponics flora series now

 

[Virgin Ground]

Pro mix, use the hydro side.

 

[Promise]

My water is in the 5.8 -5.9 ph range, so I'm right in there, this is a great bit of info, thanks

 

[Virgin Ground]

Sorry. I thought it said you were feeding at 6.5.

 

[Promise]

Sorry I meant I was going to flush the plant with 6.5ph water
