Discolouration on Blueberry clone leaves

The roots popped out a few days ago in Root riot but the leaves are beginning to turn light green & the higher leaves are wrinkling as if lifeless.

PH is at 6.0 (my last grow did ok at this PH range).
Growing in small pots of clay pebbles until roots grow a little more.
No nutes.
Temp 25C.
Humidity 35%.
Misting the leaves with every watering.
The 4 clones are under 2 x 18w fluorescents.

So any idea what Im doing wrong here?

its a nute diff. perfectly normal for clones. once you start feeding them they will green right up. they are looking great.keep up the good grow.

Em I dont think theyre looking too good judging by the leaf structure.

Im guessing I should begin feeding them maybe at a 1/4 strength, what so you think?

shit they look better then my clone after rooting. i don't start feeding mine tel the 3rd week after they root. once i start feeding in a few days they start turning purdy green.

perhaps a weak foliar feeding solution untill they develope sufficient roots to feed themselves. They're not too bad i dont think. They come around either way i bet. Good luck.

I heard blueberry is one of those tricky strains to clone..where afgoo will root in a weeks with 100% near success..blue is much more tempermental...but i think they look like new clones..except for the 1 thats growing shoot is browning..and all crispy.. hey if u lose just 1 thats acceptable right?

Ive lost a few clones in the past & when cloning in clonex it take a little over 2 weeks to root but with rooting powder Ive heard it take a week. But its true that Blueberry can be fussy about the environment its in.

i do belive blue bery is a colder enviroment plant. they don't like the heat to much. anything over 73 degress w/ that strain is to hot.

Any idea what PH range I should aim for with these clones?

to be perfectly honest when i clone i do not ph nothing. 95% succsess rate. after they root i do ph at 6.0

I've had clones root in 5 days using cloning gel and using rooting powder.So I don't think that using powder or gel matters I think your humidity was to low causing your plants to be dry and hot.

My humidity was in the 90s. I cloned in rockwool which took more than 4 weeks so I tried cloning in root riot which took 15 days but many growers on RIU claim that rooting with powder works best for their BBs.

I never PH for fresh cuttings only when roots are established.
Do you use soil or hydro?

My best luck with Blueberry has been utilizing rapid rooter with 5ml per gallon mix. The first few times I also had the yellowing and even some yellow freckles fan leaves. When I diluted the rapid rooter to 2.5 the new sprouts cleared up. I also set the spray jets to 5 minutes on and 5 off. I continue this process and I have a nice harvest - clone to harvest takes me about 60 days.

I run my ph at 6.5 and use mountain spring water (live at 9,000 ft.) after chems. My temp in grow room stays at a constant 72f. This seems to work well on all strains. Currently growing Russian Purple Hash, AK, and Blueberry and they are all doing quite well. I have had best luck with half strength on ALL nutrients.

At what PPM do you feed the BBs?

How about some pics.
