clones: leaves gettin brown!!!

So, i just got two clones. they were cut about 5 days ago. i have them in rock wool. i keep the area misted and the plants always enough water. i am using bottled arrow head water and a grow light from the home depot. What could my problem be to make the leaves start to turn brown????? PLEASE HELP

Pics would be nice of the setup and the clones them selfs and whats the ph of water what root juice did you use need more info man

the ph is 7.

and im not sure what kind of rooting solution the person used

when using rockwool, you have to make sure about the ph, I forget if it's high or low but rockwool is too much of one of them. How long do you leave the light of for? Plants like dark for rooting. should use 18/6 for clones.
Do you have a ph meter or are you just guessing that's its at 7?
They look healthy now that I looked at them. What browning are you talking about? Are you using any nutes?

i leave the lights on for 18hrs. i googled the average ph of arrowhead bottled water thats im using..on the edges of the leaves it has started to turn a brown/yellow. just little marks tho..dont wana mess anything up in the early stages, ya know?

If you are cloning in rockwool, all solutions should be 5.5 ph.

if they survive the first night, they should survive for the next two weeks.
did u use a rooting gel?
r u putting a humidity dome over it?
using bottle water might not be good, cuz sometimes bottled water is just tap water.......only in a bottle
