4-Day Trip Watering Plan (12L Pot, 19-Day Seedling)

None of this should impact watering habits, which tells me you are not watering correctly to start. 1) fully saturate 2) wait for heathy dryback and repeat. That's it. Nothing special about irrigation or nor sophisticated processes etc.. Definitely don't whimsically choose the volume to give. You give the volume to accomplish the task. If you wait for a similar dryback each time, it will require a similar volume you can predict and plan for. So, the question is how long is the duration between irrigations? It gets successively shorter each cycle as it grows into pot, so take that into consideration. If that length of time is shorter than your absence, you will need someone or something to water your plants. As far as fertilization.. as you normally would, too.. this depends on how strongly you mix your fertilizer... every other? every third? Added once a week? All of these 'can' work when done properly. Use more deductive reasoning than inductive.. top-down reasoning leads to avoidable mistakes.

I would recommend getting an automated drip irrigation system for trips. But I would water right before you leave and also turning the light down low can help keep the temps down and the evaporation of the water in the medium. At the very least, worse case scenario the plant will survive 4 days without water. It might not be happy but it will survive just fine

I'd say water Sunday with up to 0.5 - 1 L of water (5% - 10% soil volume). you want to water until you see run-off and then let it dry out, plants want a good wet-dry cycle. If the pot is fabric, it will dry out quicker so water with more. I would also go with a good nutrient feed. It looks like you are using organic fertilizers so it's much harder to get nutrient burn compared to chemical fertilizers. This plant looks healthy so far, so you're on the right track. Lastly, I would say your first plant was not burned, if anything I would say it was a deficiency. hope this helps. Good luck!

The plant looks healthy and growing well. I would say hold the course and do nothing different.

I suggest watering 500ml Sun before departure, with light nutes. Don't just water the base of the plant, water the entire area to encourage root spread. 4 days seems like an eternity when they are this young, but she will be fine as long as your environment stays stable.
