I wanted to plant my seedlings earlier so I can start a new grow immediately after harvest so I had some seedlings in a 12/12 setup for couple of weeks. Now that I've harvested and switched to 24, they seem stressed and one of them looks like it's dying. Can this be a reveg stress? I've planted them in coir and fed them with gypsum, epsom salt and a little of normal hydroponic nutes which normally works great on my seedlings. What can I do? Think going 18/6 will help now?
it may be too late could you not have found a closet or cabinet to grow them at 18/6 for the 2 weeks instead of saving time you may have lost time hopefully they can recover any pictures?
They may grow give them light 24/7 don't let them dry out you will know in a week or so I think they may make it
go buy some normal soil like fox farm ocean forest, mix with 30% perlite and restart obvious your soils are outta wack, check the water run of for the PH, use pool strips GWE Cannabis Nutrient Burn good luck
I don't think it's that. I normally don't have this problem. And this is supposed to be quality coir, mostly. See the big chunks? And gypsum + epsom salt usually works really great for seedlings.
101- Did you wash the salts outta the coir? https://www.cocoforcannabis.com/community/the-soil-section/washing-coco-coir/
I didn't know it could cause nutrient burn, have not had this experience before. But I'm going try flushing a bit now with pure water. Thanks!
only remotely the deal is they are really burnt, you won't know the real cause until you get a ph reading, that is the start of your investigation right now if you had a cloner bubbler you could put them to that for a week until greened up
Tbf, I did feed them a lot of epsom salt but it was after I realized they were dying. Maybe I gave them too much epsom salt and made them die quicker but I think you are underestimating the reveg stress.
