Plant problem

Hello,i planted the germinated seeds on 23/2 in canna terra professional,
watered them at about 2 days with no runoff as i don't have trays yet
and yesterday saw some brown signs on the leaf,small brown spots on the interior of the leafs not edges,
watered them with 6.2 ph water and 3-4 ml Rhizotonic in 5-6 liters of water,the recommended is 40ml in 10liters of water
I ph down with lemon juice,i'm planning to buy a ph down



this is the whole plant
temps at 20celsius,rh 60-70
as i read on other threads it may be calcium defficiency but i dindn't saw any plant that looks closely to mine
so what do you guy think?

Calcium deficiency

Thanks for the reply,caused of what?from what i read i don't have to supplement this soil

Slightly overwatered is all it looks like to me. If you back off now , they will recover fast. They are still healthy. It could also be caused by too much light.

well the lights were too close, here is the meter after i lift them up like 20-30 cms,now it is at 1 meter above canopy

and this is how they look

what do you think>?

I say overwatered - there is plenty nutrients in those pots for the plants to use - your goal is to get the pot full of roots while not over watering. You want the roots to stretch to the edges and they will only do that if the soil is moist along the way without making the bottom soggy.

i read that i'm fucked if i let this soil dry up,in the past i was putting like 700-800 ml water in each at about 2 days,last time i put a little more
the ones in dirt i put a lot of perlite,when i put water in them the water just disappears through the bottom )i don't think they are overwatered,i worry about the canna terra ones

Well , its kinda that way but not that simple. You want to keep them moist in coco but if it does dry out, its not fucked.....just need re-hydrated asap.
The lights being so close is the reason they are not praying upwards. You may be able to up the food and Mg and maybe they will look better but in my world you raise the lights and everything will come back to life. (simply too bright for our environment/growing methods)

When the water run right through the pot onto the floor , then your soil is too dry. BUT its easier for you to manage too dry then it is too wet. Too dry just means you'll be running a bunch of water onto the floor. Too wet and its very hard to fix.

The ones in soil and perlite.....maybe water them like normal , then a half hour after you water them , water um again, that way they retain some of that water. The ones in coco are harder to tell by looks as the top always drys out fast.
Either way , too little water is easy to mange vs too much water becomes a major rot.

It's peat moss my friend, CANNA TERRA PROFESSIONAL not coco
