Sorry, not about the weight of the photo, here it is again

Brave man attempting dwc for a first grow. If you don't understand what's going on what chance do we have? Ambient temp 80F, if your water sitting above 77F bacterial growth explodes 10x. Roots go above 68F, no good. Oxygen runs low even for a little. Not good. Is reservoir light proof? Is it fairly air proof? Dwc is very finniky, too finniky for me. Hope you get some answers to help you with your problem

You see those water droplets on the leaves in some photos? That can cause lensing of the light and burn the leaves. Not sure why you would be giving them "bloom" nutrients when they aren't even adult plants, but your grow style is unnecessarily complex for a first time grower. Good luck.
