I actually do the same 24-7 till rooted
They will look worse before they look better also they may shed the ild fan leaves and what not watch for new growth this will tell you that you are rooted
Foliar feed them until the root also helps keep them healthy
I would see what wherever you’re going has reasonable price on. If you’re already using ff stuff, grabbing something from their line probably makes sense, should be included in schedule to see when best application points are.
Otherwise, some super thrive should be easy to find and has multiple uses, as well as being a proven root growth stimulator.
Since your using the foxfarm line go with thier foliar spray flower kiss
Also suggest you look into the dry trio they have for flowering work great i still use it and add it to my Remo nutrients as a bloom booster
If you placed them straight into soil you can be waiting several weeks to a month for confirmation they are rooted which is why most favor pods or pellets of some sort. Some wilt is normal at very start and your temps being 77-80f are not too friendly for a plant with no roots as well you want them under low light levels or further distance from light. Clones have little need of intense light in that all their energy should be focused on rooting not growing so though lights should be on 18/6 atleast intensity should be minimal.
