When to move rockwool seedlings to dutch buckets

[gdgdad]

The plants seem to continue to “recover”…. easily the top 1/3 of each plant is lush green, fuzzy, no yellowing on the leaves (see pics). I went through and counted all the flowers I could find (albeit some VERY small) and came up with 35 (again see pics). That’s across all the plants, one plant alone having 12, and 1 an actual tomato (no end rot either!). I know there should be more than twice that many flowers, but I’ll take whatever goes all the way to fruition. On cloning the suckers - what’s a good “length” range to place them into the cloner? I’m leaving all the suckers I see right now (only 3 or 4 since trimming, most not over an inch) until the parts I ordered to re-assemble the cloner come in. Cool nights are still forcing me to wheel them into the garage at night. The reservoir sprung a leak, so I replaced it with a much higher quality Tote, and mounted it on a “skid” plate for moving. I was concerned I might be over watering (some droopy leaves when I first got back) so 2 days ago I changed watering to off 30 / on 5 - your thoughts on that and what signs do you go by to tell you to little / too much water? Thanks!
PS - Whats the secret to getting pictures to rotate how you want them? I'll rotate them in a different app, save, and they still come in sideways!
