To add to my first post . If you can see in the pictures the end of the leafs is quite dark green and the rest of the leaf towards the stem is yellowish. I also do not prefer to water everyday to this phase because there are no roots developed yet. From the last watering 5 days ago the water has not moved more than 1.5 cm from the surface of the medium so its a fact that there is plenty of water inside and i do not want ro risk overwatering once more. I plan to give some nitrogen in the next watering targeting around 400 PPM. Of course that depends on what i will learn from this thread.
I followed your advice and watered again about 50 ml for each plant at about 275 PPM. PH 5.9 . I will provide the news in some time. 10 mins after the watering and the leaf temperature already dropped to 25 C.No offense but coco doesn't care what you want - it needs to be watered daily and as the plants grow that will increase to multiple times a day.
I think you need to do some research on growing mediums and understand what you are using and why.
I have 4 day old seedlings in soil that get watered daily. You are in coco.

Thank you man. Really appreciate. I knew that i need to water coco every day but last time i overwatered my plants in the same pots so now i am a little more fearful. Since the yellowing i commented above came after the sudden spike in watering volume i thought i did it again. I have been overwatering the last 4 grows. I ve killed like 40 seeds till now in a matter of 5 months and paid like 100 euros for every 10 of them. So i think you understand my hesitating actionsDon't be scared of water. Coco with perlite is such a high porosity medium that water funnels through and doesn't get soggy at all. So unless you're letting the pots sit in constant run off and you're not letting them dry back then you shouldn't have over water issues ever. That's the main reason people use cico/perlite is for the extremely high porosity and drainage. But this means you need to water more frequently.
Hopefully that helps a bit!

I know but the climate does not let me . I do not have an air condition so i move my tent temperature as low as the room ambient temperature lets me. So in order to have the leaf vpd under 0.8 that is the lowest i can go in temps and Rh.ps try to get your RH to the 60-65% range 70-80% is really messing up the transpiration
If you intend on growing you're going to have to control the environment somewhat. Humidify if too dry and dehumidify if too humid. Fans to keep the air moving will help with the temperature as they can take the heat but without the humidity. Buds don't do well in high humidity and mold can set in pretty fastI know but the climate does not let me .

Depends on the nutrients used but typically you start at about 400ppm and work up to 800ppmI can definitely understand you're hesitation. I don't grow in coco but I do use very high porosity soil that I tend to treat like coco aka I water quite frequently. The pots get fully saturated until a tiny bit of run off and then I let them dry back.
My soil has EWC added so they get enough starter nutrition for a few weeks and this is where my education for you is limited. Might need @Aqua Man to help you out with starter ppm etc for the first couple of weeks as I really have no clue.
You both saved my time once more and once more i have improved my knoledge by a little more. It seemed that all these days the plants were having lack of water and nutrients. I watered my plants yesterday about 100 ml and i watered again today till runoff (about 140 ml water and about 50 ml runoff ) and as @Shaded_One said , indeed i had to water every day in coco and indeed there was space to do it. The plants had their colour returned and signs of growth have already started.Depends on the nutrients used but typically you start at about 400ppm and work up to 800ppm

This is how you keep a good control of the rootzone.You both saved my time once more and once more i have improved my knoledge by a little more.

I have one more question for you which i do not want to ask in another thread since i believe its easy to answer
I always water at 5.9 PH and today i watered at about 450 ppm. My runoff though was at 6.7 PH and my ppm at about 650.
How to adjust my PH and PPM every time to keep the PH and EC at a stable frame. For example in the next watering how much should my PH and PPM be in order for the runoff water to be at 5.9 PH and the ppm at less than i have fed the last time? ( which means that plants have consumed some of the nutrients i have provided i suppose )
I use tap water which i have inside a bucket with a bubbler working 24/7 . I use Biobizz nutrients.This is how you keep a good control of the rootzone.
are you using tap or distilled and what nutrients?
HOW TO WATER COCO FOR BEST RESULTS.
Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...www.thcfarmer.com
No need to bubble the water… if it has chloramines it wont make any difference anyhowI use tap water which i have inside a bucket with a bubbler working 24/7 . I use Biobizz nutrients.

Thats very helpful.I mean its not a bad thing to do but a couple hrs will stabilize the gasses and PH.
if you want to rid it of chlorine or chloramine you can use 1 gram per 100gal of ascorbic acid (vitamin C)
