Droopy
the linked pick, please click on the image once the link loads to see it up close.
this is 1 plant of 12, on the front left, not 4 days ago it looked just like the plant to its right.
I have checked the dripper it is working, I have elevated the smaller tray it is in (inside a bigger tray) so the roots are not sitting in any standing water.
the other 4 of that strain are all vigorous and doing well, as are all the other plants in the system.
any ideas as to why it looks totally fucked up and all the others are fine? I have already flushed it, as well as flushing and reloading the reservoir, and testing the dripper to ensure that it is getting fed. waited 3 days for any changes, but nothing, so here I am.
edit: PH is 5.7 -6.0, ppm was 800 prior to flush, and 800 after reload. they have been watered 30 mins 3 times a day for the last 3 weeks 5 days. I cant set the timers for less than 30 mins at the moment, but am going to buy a more advanced timer soon.
