Droopy leaves and some other questions. PLEASE HELP!

[wawacaptin805]

Hey I have just started a bubbleponics set-up and I have a couple of plants that are giving me some problems. The pineapple kush plant has been in the set up for 3 or 4 days and was doing good the first couple of days and has now decided to droop over. Im not sure if it is due to heat stress or overwatering because this plant hasn't shown signs of roots so we give it a little water on top of its rockwell just to keep it moist. Also the sour diesal plant has been droopy. It's been in the set-up longer and is getting the same treatment as the pinapple due to the roots not being big enough yet. Can anyone tell me what problem I am facing here?

And I also have a couple of general questions I need help with:

The other picture I left thats titled spots is one of our blueberry kush plants thats doing really good, but these spots came up. And I sprayed them one day and I think that they are water magnification burn spots, but I just want to make sure I'm not wrong.

Also what is the perfect PH level for a bubbleponics system? Ive heard in between 6.2-6.4, but just making sure again.

Please Help Me!

ph should be closer to 5.8-6.0. your plants are getting to much water. you might want another aerator in your tub. if the roots are not coming through yet then wait to water the cube until it dries some.
