Hello everyone!

i got some seedlings sprouted so i have a question. I water them with little water each time (since they dont want much water) and weak nutrient solution. So my questions are:
-are salts building up?
-will i have to flush the coco when my babies grow more (like 2nd or 3rd week)?
-or should i water my baby seedlings with runoff so any salts will be washed away?

I use flora trio and advanced nutrients cal/mag

You might wanna look in to switching your Cal/Mag to their GH brand, "CaliMagic". Has 100% less Nitrogen.
But you're only going to need to water a seedling in coco when the cocos entire top layer is bone dry. Otherwise, it will get logged with water and stop stretching its roots on search of moisture.
Pot size?

Damnn i am watering like 2 times per day but like 50 ml per seedling. My pots are 11lt.. The local store doesnt have CaliMagic. I wanted to buy it from the start since its the same company but they didnt have it

Hey folks! Jumping in to ask a q.
I also read coco should never be allowed to dry completely, water at least once a day, irrespective of size.
I have just started my first attempt in coco, and im confused.

Without pretending to understand the chemistry behind it, i read :
Coco must be fed daily. In order to overcome the cation exchange capacity of the coco, and never allowed to dry completely, event the top layer.

Also starting my first attempt in coco with cuts just rooted, im glad i have a few looking a bit rought to see if what im doing is right and gets them nice, green and healthy again.
What im unsure with is when i mix my feed and set the e.c. which states
1.8-2.0 on dutch pro chart and my water is say for instance 0.8 do i set the e.c 2.6-2.8 or still at 1.8-2.0 i cant really find much on it
Im using this coco clay ball mix 20200909_152312.jpg

im having a problem finding the right amount to water to each plant ive noticed some a drinking more than others i just want to make sure because ive seen multiple sources say never let you coco dry but then some people are saying let it dry to bone dry before watering till plants fill in the pot abit more then others saying always water for 10% runoff and you cant over water coco so here ive tested the two in front i didnt let dry and the 2 in the back i have been letting get fully dry ontop before watering and these are the results over the last 3 days so assume the two in front are over watered ? the 3 smaller buckets are just average soil on a every second day watering schedule i currently have my light dimmed too 25k lux and about a meter above canopy , is there anything i could be doing better open to any advice this is my first time , ive also noticed the tips of the leaves slightly hooking down?
they are also being fed canna coco a+b cal/mag and ph balanced water
all at half dose of recommended feed cheers guys
