Clones Yellowing near tips and middle of leaves. Taking a while to root PLEASE HELP !

hello peoples.

this is my 2nd cloning attempt, and as you can see, im running into some issues.

the clones have grown a bit since cutting, but they are yellowing a bit (see pics),

There about 12 days since cut. They have a few roots popping out but not much.

The strain is OG kush.

What Ive given them so far is PH'd water & Clonex spray (1st and 2nd feeding), and a tad of Superthrive and Rhizotonic and there 3rd and 4th feeding.

PLEASE HELP ME IDENTIFY ANY DEFICIENCY!!!

They don't look too bad. I get great results with rooting gel on the cut, rooting solution mixed with azos and super thrive, soak plugs well and leave a 1/4 inch solution in bottom of tray. 80%+ all day. I think you may be wasting your unused plugs.

I have had this problem before, and there is a few things you can do. When it came to my case, my plants, just needed some cal/mag since I wasnt feeding them nutes while they were in their rockwool. So I didnt just spray cal/mag on the leaves, or feed them with nuted water. I used massbooster and facilitator from aptus. Just mix and spray and its very simple and it should turn those leaves back to normal. BUTTTTTTT.... just remember there are many reasons why this could be happening, so with the information given I think this is the best place to start. Hope this helps.

12 days from cutting, I think you shouldnt have that much moisture in the dome come day 12, first 5-7 days ok. After that I start to shake the moisture from the lid, open the tabs a lil, start shedding some of the moisture in the dome otherwise they will never grow roots IMO, they dont have to when the air holds the moisture for them. Im usually lid free by 12 days, stay on them after 4-5 days, day 2 exchange the air inside everyday after to prevent molds and mildews. Day 5-7 start opening the vents, take the lid off for few minutes then replace it, repeat this everyday day hardening them off. This method has me at 80% bad days and 100% good days asfar as success. GL keep practicing. To much water is bad, dont let water sit in the bottom of your tray unless its day 7-14 and your cubes have dried out, even then let it sit in there overnight then drain it!! Its normal for clones to start yellowing, its a race against what nutes they have stored in them VS the time it takes to get roots and uptake more N. Nute your mother good, make sure your cuts have good lighting, all that equals more power/time in your cuts.

Thanks for the help guys!

Plant the ones that have roots.
Like was said before, Rooting gel, Rooting Solution. Warm Temps.
Your plants might not have any roots, but they are still feeding from the xylem, a Rooting solution will provide food, and promote roots. I wouldn't foliar feed right now. Your Stomata are prob. closed because of the condition inside of the dome.
You don't need all that light. It just makes your cuttings stretch. Like in your last picture. Put something on top your dome to block some of the light.
You wanna grow roots, Not Veg.

I thought if I kept the light far it would make them stretch? That's why I have the light so close. It's a small t5 light for clones so its not too hot at all.

Also, most of them have 2-3 roots popping out if the cube, but not a bunch of roots like I see in some pics. There 2 weeks in today, is it recommended to transplant today or wait till they have more roots?

Either way is fine. You should most likely leave them in there for a little bit longer to ensure that you have plenty of established roots in the cube. Just don't let the cubes become too waterlogged, keep spraying the leaves, and they should begin to send out plenty of roots once they sense that the water is drying out. Not to mention, OG is on the harder side to clone with
