Dark Brown spots on recent cannabis cuttings

I have had these cutting in a turboklone for 4 days, humidity dome on, humidity has been pretty constant around 50-80%. Temp inside dome has mostly been about 75, some times higher sometimes lower, but mostly right around there, and the water temp has been maintained at about 70 as well. Just today these dark spots have appeared on the leaves. Not sure what, I am concerned that it may be some kind of mold. I have only had strait water with a ph of 7, and only a tiny bit of rooting gel when the cuttings were taken. I just changed the water and rinsed the res. All of the nozzles are spraying just fine.

I have an 180 watt led about 18 inches from the top of the dome, not sure if they could handle more or if that is too much.

Any help would be appreciated. This is my first time taking clones. Thank you in advance.

Ahhhh a common problem with clones that when one is fucked up they all are. anyways id make sure ur soil is not overwatered and the light doesn't seem like it'd be problem. it doesnt seem that plants can get sunburnt. lmao.

you need to drop that PH down for one thing ,make take a better look at the rooting gel to see if it is still good .if it was in soil i would say that was phosphorous issue but it isn't in soil ,my guess is PH

The ones with the black spots could be the start of mold You need to take the dome off and make sure you don't have a fan blowing on them. I just went through this the other day. I messed up a whole flat of clones You should use a weaker bulb or not put them directly under the light it should help them go into survival mode and push some roots out.
