I always seem to have trouble transitioning from another type of growing to the under current.
I had the same thing happen to me all the roots that grew in the ebb flo fell off and died i called uc talked to dan he told me this happens when plant are transitioning from a flood and drain he told me to a airstone in the table and keep it filled all of the time! hope this helps
What up Cross.. Glad to see you banging out another round. I'm very jealous, I look forward to a Pro run. I can't wait to see what you do with her. How big will u be letting your girls get before the flip? What's your Target hieght?
I know your experienced in the UC, I was just thinking some basics. Where is your water level? What medium did you clone in? Are you top feeding for the initial switch into the UC until your UC roots start popping? Two runs ago I had two girls that had the same look starting into the UC after I stopped top feeding, I had stopped top feeding because my roots had begun.. I raised my lights up all the way, dropped my water a bit and crown fed her a little longer and she popped right out of it. My guess was a shock from roots being able to dry up some from the ebb flow to always being under water. So I dropped water level and let the roots strive for that nice cold water below. Within two days they picked up and within 5 I raised water level back up and went for the head of roots we all want. I'm not sure if I read mine right and that worked or if it was time itself. But I think when starting with established plants from ebb flow starting my water at the bottom of the buckets and crown feed till roots start and began to thicken some helps, then I raise an inch or so until I get a solid root head started and then I drop again. I think making the roots get to that water they will end up living in instead of just popping them under water has helped. Just be sure to top water a cup or so two to three times a day till those roots hit the water.. I hope it all pulls out for you. Best wishes brother..:bong2: Ohhhh and I think your EC is fine. I start mine at 300 ppm on a 7scale when coming from 700 ppm off ebb flow.
Looks like they're reeling from some type of stress beit chemical, light or otherwise.
What level do you have the water level at? During this transition you'd do best to have it a few inches up the net pot to ensure a well hydrated plant during transitional stress.
Also consider foliar sprays of a dilute sea kelp solution.
Don't sweat this too much though, assuming ur conditions are good ur plants will likely turn around.
They dont look to bad Ive seen a lot worse in transition. Raise the water level like uchq suggest. Theyll bounce back in a week sure of it thats shoick
How do the roots look ?
Yes they just looked stressed to me. What was the temp of the water you were flooding the table with? If the room temp is 75F then your root temp was probably around there. Dropping the roots in a water temp that much colder all at once would also stress the plants IMO.
Is it just the camera or do your plants get smaller the further away they are from the epi? Mine did the same thing. I chaulked it up to different temps. My setup seems to run cooler on that side of the room.
I had this issue at first switching from flood tables to RDWC. In my case, I realized that there was a significant difference in temperature between the reservoir and the table when it was flooded. I kept the res at 62-63, but during flood, the water in the table was in the 69-71 neighborhood. Keeping the E&F Res at 55* made for a relatively painless transition to RDWC, but my chiller wasn't happy. So instead, I know keep keep the UC at 70, and drop the temps 2 degrees per day over the next three days.
I still veg with a flood table, and as long as increase flood times leading up to the changeover, and the UC water temp is the same as the temp in the flooded table, the transition is smooth.
Additionally, with CO2 I see better results in my garden if I the air temp is up closer to 80-83, and higher RH, somewhere 65-70%. And FWIW, I clone in 1650 ppm CO2, no problem. Once flowers are forming, I start backing the temp and RH off. In veg though, I see a huge difference in growth rate when I keep the temps and humidity a bit higher.
