I’ve been struggling with the growth of these seedlings.I don’t know if I’m under feeding them or overwatering them or maybe poor drainage in the growing medium.kindly help me of what you think is the problem.I’ve done everything I can but seems not to be working .They were many and a lot of them died but checking carefully they had problems with the roots and I don’t know the cause

Like any good detective, you need to look for patterns, so if all of them showing the same signs, it means either the genetics is fucked, which is rare, or your medium is just not good for them, if you say the roots are bad on all of them, then I would say change your medium, check your water ph and ec levels.
Seedlings don't need a lot of water so give them a little each time until they are established.
Also, keep them in the solo.cups until they have bigger root mass before you move to bigger pots.

what soil are you useing?
when did you start feeding them? they should be ok with the soil (if it is soil) in the pots for a while without feeding.
you should have holes in the base of the pots for drainage.
if theres no drainage holes, get a stanley blade and slice a small piece of the solo cups off, it wont need much, but will save you lots oif grief down the line

Those cups should be full of holes, on the sides and bottom, especially if you said the roots looked bad. Cannabis roots need air, the soil needs to dry out so the roots can breathe. If that is coco, sorry, I have no experience watering with coco but they still need air holes in the cups.

The medium is coco coir. Are you feeding them yet? As I water mine for first week then I start feeding them a very weak mixture of nutes. What nutes are you using? If you are feeding what strength are you using? Are you getting your pH right in nutes before feeding?

Under watered/fed for sure. Mix up base nutes at 1.2 ec 5.8 pH and feed 3 times a day to run off.

The seedling are to small to feed three times a day and it is a waste of nutes. When plants are this small I never feed more than once a day. Depending on how they are doing I may feed every other day. @Kola_Kreator I am not being a dick I just disagree with what you said. Hope I did not offend you

Not offended at all. That Coco looks very fibrous and airy and it looks way too dry. There's no risk of overwatering and I am 90% sure that this would fix his problem. I run everything seed or clone in Rockwood for the first 2 weeks and I keep it half wet most of the time. I then transplant to Coco and my watering kicks off at 6 times per day. Any less and I get underwatering issues.

Don’t the EC meter just ordered one .I only adjust the pH for now

Well it is important tool to have. That is the only way to tell what feed strength is. I would just start out by looking at label on product and whatever it says feed only 1/3 of that just to play it safe.

I'm going to theorize that complete crop(9-5-15) is a little lower in nitrogen than I would use for plants that young. You might wanna add some nitrogen, but keep the ec down, while they are young. Drainage would be good. How close are your lights? What soil are you using? A little more perilite would not kill your plants next time.
