Edit: I'd call this drooping, not wilting, can't change title
First time with Ebb and Flow. I have the Sentinel MEF-1 system using Dyna-Rok II grow rocks.
After transplant I seemed to be watering them a lot to keep them from drooping, but my humidity is really low currently (25-35%). I figured once they developed some roots I'd be able to dial back, and every couple days I'd try extending the time between floods but they'd end up drooping and I'd end up going back to about every 90 minutes. Every time I've tried extending it to 2 1/2 - 3 hours they'd end up completely drooped, even when the rocks were visibly still moist near the surface and certainly moist below the top layer.
My temps are easily managed, I'm running 2 600W Metal Halides with air cooling. I dialed them up to 750W at one point but they were drooping a lot again so I raised the lights a lot and put them back to 600w.
I didn't quite fill the pots to the top with rocks so I thought maybe the light was getting in there and killing my top roots, I just filled them up to the top 3 days ago and no improvement thus far.
Searching around on here and various places, most of the time people are suffering from over-watering, some say their strains sense when it's close to lights out time and they naturally droop before that happens. My strain (UK cheese) has never done this to me growing in Pro-Mix or coco unless they are totally dried out. I did however change from 18/6 to 20/4 lighting once I thought they were established and they usually seem to be wilting some time before the original lights out time (although I'm usually sleeping until around that time so it's hard to say for sure when it's starting.) I go up there and check on them, see they are wilted and give them a manual flood and turn the lights off and 5-6 hours later they come back on and they recover. I still have to water them every 75-90 minutes or they wilt. I just tried raising it to every 2 hr again yesterday and at first they seemed fine but were drooped again today (pics at bottom)
To me this doesn't look like overwatering, the leaves are not curling or twisting and they are very lifeless, the stems are soft and bendy too.
I'm using JRPeteres Hydro + Cal-Nit @ 650 ppm, started them at 400 and did a res change a week later and raised to 650, couple tips burnt here and there but nothing that has progressed.
The dyna-rok is filthy, I rinsed them for HOURS before putting them in and still my res is full of it's mud/sand. I did a full res change and again it's full of it so it's hard to monitor my PPMs at the moment, so if anything they are being underfed in my opinion because my ppms are rising and I haven't topped it off at all as of yet. Hoping another res change will get most of it out.
Any suggestions or wisdom? Most people are only flooding 4-5 times while lights are on from what I can see, so I can't imagine mine should need water every 90 minutes even with low humidity since the rocks are only drying out on the very top by the time they are drooping.
The first pic is from a few days ago before I topped off all the pots with more rocks, you can see they are clearly wet.
