Clones are bronzing, new thing cant figure it out

Hi there all and I appreciate any help on this one.

I've been succesfully growing for awhile and the one area that I can't seem to get down in cloning.

I finally thought I did though and now I have a new development.

Where the leaves are from the center they start to bronze, a light browning starts to go all over the new leaves and eventually dies.

I can't figure out why it's doing this. I've cleaned the trays with bleach and soapy water, switched mediums from Peat Pellets to Rockwool cubes, never resued and sit them in a nice dome. I can't figure this out, any help???

1) When I first started out, I bought a CFL (Can't remember Kelvins) - but it was basically a work light. I saw similar "bronzing" and eventual death you did.
a) What type of light are you using?
2) How often are you watering?
a) What are you feeding them?
3) What type of hormone powder/gel are you using?
4) Are they under a humidity dome?

Answer these questions, and we will see if we can figure it out.

Well for the cloning stage I'm not using any light. They are under a dome. I don't water them at all just have the cubes damp enough to not require anymore. No feeding there is no roots. And I use Stim Root poweder.

I hope we can figure this out, one theroy I heard was that the mother plant may have to much nutrient in it and the plants leach them out into the cubes when they are placed in.

Ok - here is my advice: Start a whole new set of clones, and make these adjustments:

1) You definately need to put these under a light. Right after I clone I put them under 1 daylight CFL T5 tube I have.
2) before first cut - Soak Your Cubes in PH'd down water. After that - Dip them half way in PH'd water just before the cubes are semi dry (never let them get dry).
3) Lift the humidity dome up only once a day.

I think your major problem is light, and possibly water. You have to get that photosynthesis going... Even though your goal is roots right now,
your plants must create the energy to produce those roots - and that comes from lights. If you are using high intensity lights, and don't have
any CFLs, put the clones on the very edge of your room to start where there is least amount of light (still light though), and make sure the temp
isn't too high.

I would invest in a small 1 tube T5 light - it will really help your clone game. Hope this helps (GET THEM UNDER LIGHT!)

Thanks I'll give the lighting thing a try, I didn't think they needed light just time to devlop roots and thought the light would give undo stress. I"ll give it a try, I need to hold onto this strain it's very sought after.

Thanks

Was the lighting the problem? How are the bronzed leaves doin?
