Clones all turning yellow . . Help please!

I made a homemade "clonenator" a couple months ago and it worked great on my first batch. I had 100% make it and they had great balls of roots. Now, I am doing my 2cnd batch using the same mother, which is Blueberry. This batch is just the opposite. When I got the 12 clones home from my buddy, they were really wilted bad. I know they sometimes stress when cut. Plus, it's hot here in Texas and it was a good hour before I got them home. I got on this site for help and changed my water cycle inside the clonenator from 15(min's) on 45 off, to 15 on 15 off and tried to hold the humidity inside by taping the sides. That was 10 days ago and only 2 are looking good w balls of roots. The other 10 are yellowing and looking really bad. I am only using "Jump Start" as far as nutriens.
These are blueberry clones under a 2'x4' with 4 t5's. Please help me try and save these. I have no idea what is wrong as I am doing the same thing as my first batch that went so well. The only difference is that they were really wilted bad when I first got them here. Yesterday, I took each clone out and looked at them. 10 out of the 12 aren't rooting, so I acted as if they were new clones. I made a new 45 degree cut up where the stem is still good and not waterlogged and dipped them each in "Replicator" and then into the Rapid Rooters. The pics I am showing are from today. I am using nothing but the Jump Start and started spraying every other day instead of evey day and that is all that has changed. Again . . . PLEASE HELP!!!. Today is 21 days since first cut.

Doesn't anyone out there have any advice? I would really appreciate it if someone would respond.

Whats your water temps? You seem to care and note everything but the most important one of all ... water temp.

the water temp is in the mid 70's. I do not have a heating pad underneath. just finished checking the girls out and no change. thanks for any help!

Looks like they need to be fed.

Good Luck

I would agree there.

What I have here at the house is "Root 66" from Technaflora. Do they need nitrogen at this time?

light?and how far down?

I realize this an old post, but for anyone scrolling through and having this issue, here’s some tips and possibilities for what went wrong. 1. Top cuttings (cuttings from the top of the plant, which have thicker stems) will generally root better than bottom cuttings. 2. Target a higher humidity and VPD closer to the lower end of the general range. The ideal VPD for clones is closer to 0.8 kPa. A humidity dome is very useful for this. If you’re unfamiliar with VPD, check out vpdchart.com 3. Cut the tips of the leaves. This stops the leaves from growing and focuses energy to producing roots. 4. Use a rooting hormone (gel or powder). 5. Low light intensity (that of a cloudy day) is best (think 300 ppfd, or a DLI of 15 to 25 mol. If you’re unfamiliar with Daily Light Integral check out Dr. Bruce Bugbee on You Tube. 6. Your aeroponics / clone machine should be running non stop when trying to produce roots from bare stems. The intermittent misting is for when they have roots and continue growing with aeroponics. Nutrients aren’t really necessary if using tap water when cloning, which typically has enough calcium, the most needed micronutrients at this time. A foliar spray with some liquid kelp / seaweed diluted 1 oz to 1 gallon is most effective. It’s more important to have a low pH around 5.5, and water temps around 68F. If using RO water, add 1/4 strength of a 3 part liquid nutrient diluted solution with added CalMag+Iron at half the recommend strength. Hope this helps.

I use a really complicated process myself. I just cut clone, dip in cheap rooting powder available at Home Depot, stick cutting in small pot of precharged coco, set out of direct light. Wait 7-10 days for roots.

looks like some ones snacking on your ladies
