Need help with sick clones

Hi there, I've got some clones that are sick and I'm not sure why is that, any ideas ? Two of them are starting to grow some roots.

First week they were in a glass of water.
Second week I build this cloner and put just water inside.
Third week (this week) I change the water and add some bio-grow on it coz I thought they could be lacking some nutes.

Do you know why are they sick ? Was it a good move to add some bio-grow ? bio-grow is supposed to have micro-nutrients in it as well.

Here are some pictures:

The problem started before, that's why I added the bio-grow two days ago, added 1ml for the two liters of water (0,5ml/L).

the thing is when clones are developing the only thing the plant should have to focus on is growing roots,....they dont nessesiarally need large amount of nutes beacause the clones are now using energy processing nutrients instead of developing roots,......you should p.h your water at between 5.0 and 6.0 with them being babies and back off the nutes its too early for that ,..id p.h it at 5.5 and play it safe,..i dont know about the cloning system your using but in my personal opnion rockwool cubes and a plain grow tray work best,....also thre probably also struggling beacause i noticed you didnt cut them at a 45 degree angle, the reason that helps is beacause it gives the plant more surface area to develope roots,....the sharper the angle cut the better the chances of rooting,.....id also try to make some type of plastic of suran wrap dome to cover the clones with there all ready in trouble and they ll need the help the love moisture,...change the p.h stop the nutes and use a cover tray and you should be fine......good luck hope it helps

Thanks for the info and +rep for you.

Maybe it can't be seen in the pics but they were all cut at 45º angle. The water this last change was ph at 5.5-6, the one used before was ph at 6.5 coz I didn't know the ph should be that low. I'll try to get some kind of cover for the humidity but it can't be because of the nutes coz it started before I add them. May cut another clone and put it there to see how it reacts.

no nutes for clones just plain ph neutral water and warm water at that. i made one cloner form a 5 gallon bucket and a mister on top to mist the stems with water. the water stays around 85 and all the clones come out fine and roots showing in 3-7 days.

yeah that sounds like a good idea i would use a process of elimination then if you were having the problem beforethen i would agin suggest keeping them coverd for a while also did you use any root hormone!!

Yes, I used some clonex but I don't know how well it works if they take 3 weeks to start rooting. I think the dome is a good point but gotta find some place a little bit further from the light coz if not it may get too hot. I'll try to get it done tomorrow :)

Also I threw away one of the clones and cut a new one, this time with bigger leaves and a bit taller. Hopefully I'll get a better result with this one.

Anyway, it's kind of crap coz I got two tomato clones at the same time and they are rooting amazingly well lol maybe it was too son for the mj plant or the clones were small and weak.
