Unless your ‘starts’ have two or more ADULT leaves, then, no. Seedlings don’t need fertilizing until then.
Can you put the milk in the freezer while you are gone? Milk freezes just fine; no need to waste it.
BUT - if you have to dump it, water it down and feed it to any potted plants you have, inside or out. Also, give it to any flowering shrub in the yard. :)
Thank you!
If full containers, pour a little off before freezing because liquids expand when frozen. A full just will pop the lid off and spill over before totally frozen.
When I tried to freeze some 2% milk a few years ago, for a camping trip, it thawed sort of “granular”. Like part of it was trying to become fine grain cottage cheese. It still tasted ok, but looked kinda weird. It seems like I tried skim too, without that effect. I won’t swear I don’t have that backward.
