possibly nothing but.... PH? stunting?

[bgrt]

hey so im growing: White siberian, Sour AK, Jack 33 + Easyryder x2.
theyre under about 160watts of th50 5x6500k and 1x3500k. until yesterday i also had two 35 watt 6500k globes to the side of them and i was hoping any cupping was just a weird way of getting as much light. but thats very hopeful.
took them out just incase they were drying them out further as i had to have the fan on a bit stronger to help cool things. they proably didnt need them anyway.

im pretty sure ive stunted them,
i germed straight into the soil and all popped in 48~ hours. the soil is canna seedstart or whatever their low nute/no nute seedling compost is and added perlite and vermiculite. i used the same seedstart base last grow with two easyryders and some rrf's and they had no problem though i never added perlite etc i thought it was neutral ph wise though and wouldnt hurt anything. but i think these are stunted and im assuming the ph is off or something similar. i havent added any nutes myself and only water when dry or near dry anyway. i dont think im underwatering but its a possibility.
theyre about 11 days from breaking soil.

origionally i was ordering a digital ph, ph down up etc. with the rest of the stuff i needed for this grow but i had to split between two companies and with some credit card problems half got delayed and i still havent been able to get the order going maybe this week but who knows. no hydro shops so finding one locally isnt an option.

i planted some sunflowers in the leftovers of my mix just to use it for something.

now in the pics the tub full of random plants (big ones next to the pots are sunflowers planted the day before the ones in the small pots) i used a multicompost spaghum peat moss with some perlite or something similar and those plants seem to be doing way way better darker green, quicker growth, so im wondering should i transplant into a mix with some of this if what theyre in is stunting them,.. the seedlings in the canna are light green and comparing the sunflowers to the others with a day apart something is very different though that could just be the tiny pot size. (i know theyre different plants just seems like the common problem would be the canna seedbase thing.

basicly would you transplant without ph'ing etc or am i just ahead of myself and theyre just slow.
on prettymuch all pants there is leaf curl also the single white siberian seedling has a brown spot and a tiny dot of colour on another leaf. i thought i might be drying them out as rh is about 40-50 and i have a fan on them to keep down temps (70-80ish).

i would like to not have to restart but i do have more easyryder seeds and white siberians but the other two were the ones that sounded great to me so would prefer to keep em if possible. how does stunting affect photos do yiou just need to veg longer or will it ruin yield etc.

sorry for disjointed writing havent slept in oh so long :cry:

Do not over water them,and don't feed them nutes until they at least three sets of leaves.Leave them in the pots they are in and leave them dry out a little between waterings.Dont rush them,they will start growing faster with every set of leaves.

 

[Cave Dirt Cody]

How much water have you given them over the last 11 days?
Go pro active on one of them and transplant it. Take a pic of the roots.

to namvet i havent overwatered them im pretty sure and no nutes like i said. i know the dangers and the wet and dry cycle.
yeh i remember last time it took a while to get going and then burst off but this seems longer on four different strains with a different soil having much better results on basicly a side by side of sunflowers..(albeit different pots)

maybe three times watered since potted CDC, one probably being the first wetting, and only when it needed it not just that the surface was dry.

i might try transplanting one at some point probably one of the easyryders as i have more seeds, but not today anyway i shall wait a bit just to see if things sort em selves or get worse etc.
wanted to cut the bottom out of pot and tier pplant it but if the soil is an issue ill just restart a new seed in new soil or who knows

thoughts on the brown spot? just imo seedlings shouldnt have stuff like that yet without outside influence

if they seem normal fine just wanted to check before a problem starts.

EDIT: just incase someone thinks i need more light or anything this is what i have to work with, 600watt hps dimmable, probably 5 more 24watt t5hos and some cfl globes, i have them in a cabinet for now just for ease and so i dont have to make something to hold the t5s as they are single fixtures but eventually the plants will all go into a 3x3x6 tent

im using tapwater but its the same tapwater that worked fine for the same strain(easyryder) in the same soil so i was just assuming its not too high or low, no issues atall last time like this(if there even is an issue hopefully im just obsessed with fixing them).
think i should have a ph meter+ph up/down by next week gonna order tonight etc

 

[namvet]

It sounds like you have enough lites.As far as that spot its hard to say but I don't think it's somthing to worry about unless it happens to more of them.

 

[bgrt]

anyone any thoughts on the side by side with the different soils?
seems way too differrent and constistant to be nothing to me. all plants in the canna mix with perlite are lime green and small while the rest in the compost with perlite are dark green and huge.

still no tap root through pot either, not much growth and no more effects really.
ordered ph stuff there so should be able to tell next week.

Hey, bgrt. These are my thoughts..

They look overwatered to me. That soil could do with being a lot drier for younglings as they're mostly looking for air at that stage. At 11 days - and if the soil has NO nutes in it - I personally would be feeding them a very light grow feed with an ec of no more than 0.4.. but that's only if the soil has NO nutes in it. If it has a light feed in it then I'd not feed for about 3 weeks.

Couple of things to consider..

Vermiculite has a tendency to raise soil ph as it's an actively alkaline medium. That could lockout manganese, iron and some other obscure mineral that I can't remember. Plants don't need a lot of these at all but when they're young they miss them quite quickly. Not everyone has problems with vermi, but there's no industry standard and even vermi from the same company can vary from batch to batch. To be honest, vermi (and adding 30% perlite) is a practice that's about 30yrs out-of-date back when potting soils were shite. Modern soils have the right balance of air/water ratio and these days come with enough perlite for the job already in the bag.

If those girls were mine.. the first thing I'd be doing is letting that soil dry out properly. We can't put anything else in the medium to correct anything unless it's dry because we want to avoid suffocating the roots. They need their air right now. If you can get hold of any seaweed extract (biobizz alg-a-mic for example) then they'll like one dose.. 1/4 ml/ltr when the soil's dry. It'll help them recover, grow some roots and give them a mineral boost.

cheers for the info but that picture was taken directly after a watering as ive said i let them dry out, well, and have only watered them 3 times total and only when they needed it. or do you mean that im watering too much at one time.

the soil had no perlite in it to begin with atall but i didnt knwo that about vermiculite. i have a seaweed feed somewhere i might feed em that next watering. hopefully thatll help.
