Seedling trouble

Your soil have too much nutrients in it for the seeds, get a light mix , u can do a ball inside a rich fertilized soil in the same pot for autos that u don’t wan’t to transplant

The soil you used is fine and should be good for seedlings so it’s not that as I just looked it up. At this stage I normally have to feed about twice a week, looking at your new growth it does look unaffected so maybe it is growing out of it. It that was mine I would give it enough water so it only needs feeding twice a week and adjust ph higher. Forget that 100mls, it’s hard to gauge how big the plant is from the pic but I would use more than 20ml for sure. Double it to 40ml and see if that’s enough for two feedings a week. If the top of the plant looks ok I think it will be ok, sometimes it’s easy to overthink the problem pal and adjust too many things at once. I know as I have made every mistake there is to make in my early years of growing lol

Ph pen was just adjusted too, correctly calibrated by hydro store, ill adjust the ph of the water as well. Please respond, im dying here haha

I dunno if its too close but that pic of the plant its only maybe 1.5 inches tall, you think that 100ml would be drowning it? Lol im not sure because the soil seams wet at the top and a little below the surface too (not arguing, just not sure) was told i was possibly overwatering the little bugger at first and I think its slowly getting saved.......until now haha and the soil is "Dutch treat" and I was told its organic

I don’t think 20ml is enough, I would give it 100 ml right at the base of the plant. And definitely raise the ph to 6.6 just to eradicate it from the equation, have you calibrated your ph meter recently just in case it is giving you false readings? The reason why I am thinking this is the leaves are twisting which can be a sign of ph problems before you get the weird leave markings also associated with ph issues. Read the packet on the soil to check it’s ec/ppm. Is the soil organic? Ok if it’s not light it has to be ph or soil too high in nutrients, I do also think such a small amount of water may not reach the roots of a plant so that could be a factor.

Yes its a starter mix I got from the hydro store and the light is with a dome kit I bought for starting seeds, so its a pretty weak light, and I've been giving water every two days and only about 20ml at a time. And no I haven't been giving any nutrients at all yet. So you think it's a ph issue?

If that is in soil that is far too low, I would aim for about 6.5-6.7. Is the light too intense? My guess would be one of those two factors. I take it you are not adding any nutrients to the feed yet? Also I would only be feeding that 200ml a time max till it gets bigger.
