Had an issue with something with either my calmag or botanicare grow nute. Everything in my room was yellowing hard which I've never had happen before. I tried a few different things to remedy the situation, and they kept going down hill. So before they a ended up dying, I shook them out of their coco, and stuck them in my homemade cloner and set it up to dwc them, and purchased all new nutes. Theyre still a little stunted, and small, but they've greened back up and are growing again. This happened with 48 new seedlings, as well as some older bigger plants fed with the same stuff in the same room. I'm going to have to let these get up a few more nodes, then re root them to be able to put them back into a pot or basket. These are actually a few weeks older than stated, however I think at this point theyre going to continue growing now, and have been topped. Once the tops get a few nodes on them, I'll re root them in a cloner to be able to re pot them.
Glad you were able to save them. Something tells me that they will be fine!!
Sending the best of vibes to you and your plant/s. Enjoy the mutual growth you will have together! 🌱
