Hydro help please

[tyler_ hobbyist]

I did a fresh res change yesterday and since the plant leaves seem to be pulling down instead of trying to go up. Can someone help me

hi tyler,

few things come to mind.

1 - do you normally leave that filler cap extended? (bottom left in the picture)
2 - whats the pH of the water?
3 - whats the ppm of the solution?
4 - (i assume that you do, but) is there an air stone in the bucket?

something points to an unhappy root zone, thats for sure.

any air movement, with a fan?

The clear plastic is allowing light inside your reservoir. That’s bad. Rule #1: Darkness inside the reservoir at all times possible.

Hi tyler, that happens to me when the plants are young. I try to change the reservoir as fast as I can when they are that young, and leave the roots entirely alone. They usually bounce right back after a few days. My mistake last week was putting water that was too warm into the reservoir (it's coming out of the tap at around 80 F!!!) Since I keep the res. chilled, I think that shocked them.
