soil too hot?

Not sure what this is. I'm on my first grow and I'm having a hard time diagnosing this issue. It started on the bottom leaves first. These pics are a few days old but here they are:holy grail kush 3 weeks from seed
Cannalope haze 1 week from seed

They are both in black gold water hold, each under 2 60w equivalent CFLs. I flushed with 3:1 hydrogen peroxide water a few days ago and it seemed to help a little but the first set of leaves has pretty much died on both. They have been watered with 6.5 pH ro water. I'll take some pics when I get home tonight.

What's the ambient temperature and humidity in your grow space, and how often do you water?

Around 75 Fahrenheit and 55-60 rh. I've been watering when the cups feel light which can be anywhere from 3-6 days

Showing some type of deficiency
Looks more like nute burn on this one

I clipped the burned end off of the leaves on the bottom one and removed the first set of leaves on the top one

looks like they need feeding to me,

Out of curiosity what is the cayenne pepper looking stuff sprinkled on the top in the first pics? In all pictures they seem droopy, possibly overwatered. I would imagine that given the fact that your using soil designed to hold water, a flush on plants this young and this droopy can't be a safe route unless you nuked them with nutes. That soil is also fortified with EWC so it would be pretty incredible to me if they needed more nutes.

I agree that theres no way they need food. The soil should still have plenty in it plus I gave a very light feeding a week and a half ago of nectar for the gods and some bio root. I'm thinking nute lockout. I definitely haven't over watered as I wait til its dry past my first nuckle and the cups are light. I may go ahead and flush with herculean harvest as that's supposed to help with nute lockout. That's cinnamon in the first pics lol, supposed to be anti fungal

bit late to say but ph?

Forgot to update this thread. @bobtokes gets the gold star. I'm embarrassed to admit it but Im growing in a soiless mix and didn't realize it. Turned out I was water only feeding plants in a coco coir sphagnum mix That explains why they were showing tons of deficiencies.they're doing much better now

Yup yup everybody needs food, I forgot that on a big grow some years back, was racking my brain trying to figure it out, and the lovely Flaming Pie asked me what I was feed them and it was a book smack to the face, I feed them up and finished out the run with out issue. Thanks again @Flaming Pie, hope the baby is doing well!

i recently started cutting holes around my small cereal bowl/dixie cup containers; wanted to give air pruning a try. It really affects how long you can keep them in those original starting containers if you don't have much room in your veg space if perpetual.

not that they're that big yet, but i've always had to transplant before with those cereal containers

I have drainage holes in my solos and they do air prune for sure

Yea I had someone ask me on another forum, same booksmack epiphany. He was like water only in a soiless mix is a bad idea. But I'm not in a soiless........ohhhh

yea... i had drainage holes before they don't really air prune... as in eventually left in a cup in that shape or the shape mine are in the roots will eventually swirl around and stop producing new roots becoming rootbound.. of course i'm sure you transplant way before that's an issue. just thought something intteresting.

i was basically trying to make a ghetto version of these pots

You need airflow under the solo cup to get root pruning. I use a milk crate to set them on.

Ghetto solo cup airpot....I like it. I didn't realize you meant holes all over the cup. Mine are just in the bottom
