Please i need advice on a watering schedule for veg (for flowering I just water till runoff and it works well). I'm watering every 3 days with 350–500 ml, but the pots still feel a bit heavy. With 20–23°C, 60% RH, 7L Light Mix soil, how often would you water?🙏

Then, wait longer. Watering is a reaction to how much water remains in the pot. How long a plant takes to drink it down will slowly speed up over time. So, it may be 4-5 days after you pot up, depending on the size difference and how developed the roots were when you did it. By the time it's fully grown even in a final pot, probably 1-3 days minimum. So, you got the right idea watering until you see 'some' runoff. If it's soil, it's good to minimize that, unless trying to dilute soil concentration. If it is soilless, you want 10% runoff or more, religiously. That avoids buildup in a soilless setup but just wastes pre-amended nutrition in soils. You still want to ensure full saturation. That is the correct way to do it. Think you pretty much have to treat light mix like a soilless within 2-3 weeks? Just has nutrition to start plants? If you ever are supplying 100% of the nutrition through fertilization, mimic soilless procedures. 1) saturate to runoff appropriate for method 2) wait for dryback and repeat i think the best way is to learn the feel of weight loss from, some use depth of dryness. If consistent, it will take the same volume but the time between will shrink except for cases of potting up to a larger volume of medium with no roots yet. A heavy soil you may want to wait for 1"deep. Something like coco holds a lot less water, and you trigger irrigation at change of color up top or even just before that point... again i think weight is the easiest to get familiar with. So, it's a reaction to something you observe as opposed to a pre-ordained schedule. Can't fuck it up if you stick to that understanding. Don't pick the volume. You give what it takes. Don't pick the frequency. You re-irrigate as a reaction to loss of weight (dryback).. No overthinking it. The other thing that will help greatly is a properly constituted medium. Doing so makes everything easier and proper aeration/oxygenation of soil. Heavy medium should have 50% perlite or similar. something like coco only needs 33% becuase it holds less to start. In the end, both 'base' media will result in a similar gas:water mix per volume, which how each is calculated in the first place. coco holds about 2/3rds the water of sphagnum peat moss, so it needs about 2/3rds the perlite to accomplsh same goal. Properly constitute a soil and it is impossible under normal common sense circumstances to overwater. you'd have to be forrest gump to accomplish it, lol. Sit there and run water through it with a shit-eating grin for 15-20 mins and it might droop, lol.
