Sorry about the late reply - a little too much ‘life’ has been happening around my house recently.
Thanks for the information and help. Yeah, I decided pretty much the same thing. Just feed them as needed and leave them alone for now.
Right after dipping them that last time, I put the cubes into small dixie cups filled with perlite and gently packed some more around the cubes so the emergent roots (all of them have roots showin g outside the cubes) would make contact. I also cut some small holes down just above the bottom of the cups for drainage. Sort of like making mini hempy buckets.
Im bottom feeding them now by putting the cups into another container with nute solution so it raises up to close to the bottom of the rockwool cubes. After a minute or so, I let it all drain out down to the drain holes. Im hoping this will encourage new root growth down into the perlite.
Ive been doing that once a day and they seem to like it. All 5 are coming back and the new growth is looking good. No sign of new roots yet though.
