Dark spots on clones

[rdy]

Does anybody know what the cause of these dark spots is? Cuttings are 5-7 days old, Rootech and rockwool cubes.

Let me know ASAP as these girls dont deserve anymore suffering

thanks

Maybe a magnesium deficiency?

assimilation

they are eating themselves, are you using any (weak, ca. 1/4 strength) nutes yet?

Anyways, they use the stored nutes to grow (roots?), its not a bad sign imo

that is quite normal. mace ecam is right about them eating themselves. If they have roots already start feeding them asap.

But be careful, the roots are still delicate so no full strength solutions.

Thanks for the responses! I feel better about the assimilation thing.

I added a 15-20% nute solution of Calmag today in some ph Adjusted water, I think I had some problems initially from using tap water, the ph made the leaves turn on themselves.

Hopefully roots will pop out any day now, I'll post a rootshot once all is well

thanks again
