ok u guys are probably 100% right but i must ask why would i now just start to notice an issue when they have been living like this for at least 8 weeks?
That is a very good question. Perhaps they were struggling the whole time and this one finally gave in. I cannot say for sure. Your pumps definitely need some off time though. 1 min on and 4 min off is ideal.
yea its in the center of all the sprayers while the other two are on each end so it makes perfect sense that this one being in the middle of all the sprayers is getting over watered
ok one more question? the lights turned off so should i make the adjustments now or should i wait till 10am eastern time to fix the issue? keep in mine i do have an airstone under the roots
The one that looks dead was prolly taking the brunt of the overwatering that's why it looks so beat. 1 on 4 off your plants will look good if not they will all be fucked up. Overwatering is just as bad if not worse than underwatering.
It doesn't seem like your airstone is doing enough work to justify not fixing it now. There is no sense in waiting. Fix it now if you have the timer already
