Brother grower, first question, what soil are you using? Something along the lines of Promix that is pre-fertilized? Have you made any base in the planting pot? Have you used any mycorrhizae, Trichoderma, or any rooting hormone? Any kelp dilutions? Well, I always recommend, and I've been doing this for many years when planting in soil, to use Canna Professional without prior fertilization.... then in the area where you will transplant the seedling after germination (some put them in pots or plastic cups until they take root and only at the end of almost a month do they move them to the final pot). I see from the photos that you are using fabric grow pots, which are very good pots in terms of not overwatering, as the fabric can let some excess water pass through. Then, as I've said, make a good base in the growth area using mycorrhizae, Trichoderma, some rooting hormone, and all of it sprayed with kelp in solution... these things that may seem very complex to you are not, and mycorrhizae or Trichoderma help create threads that connect to the roots, greatly expanding your grow system's ability to absorb water and nutrients, so you won't need to water daily, and the indication of a grow with the perfect amount of water is noticeable if you put your finger about 5 cm deep (not too much over the central area where the seedling is and where the primary roots develop, so when you put your finger in, you don't damage the roots, because if you do, it's the death of the grow for sure.
With the size I see your seedling, from the soil structure, and I see you have perlite, but I ask if you add any vermiculite... vermiculite has the property of retaining water in the soil, and with that, you'll also have a way to keep water in the system for longer.
Since you are in an autoflowering, my advice is to start without any problem and for your soil to begin to saturate with water, start daily by putting one liter of water and don't have any issues adding nutrients according to the nutrient chart you are using. When you see that your soil is "wet," meaning that the water is in most areas of the soil, you can then, for example, give water always in the same amount (1 liter and the nutrient solution) and very importantly, the watering should not be poured directly at the center of the plant but in concentric circles starting from the outside in. Very important, and because you are in an autoflowering and because the cycle will be fast... always use water with a pH level never lower than 6.5 and never higher than 7.1 for optimal nutrient absorption, and a very important note is to water during dark periods and avoid the hottest hours of the day... if you are doing an outdoor grow or if you are indoor even with LED or HPS, avoid when you do, for example, and cannabis loves it if you do a couple of times a week with a spray bottle, watering the leaves with nutrients that are prepared for that type of watering (like the Deltas from Cannabiogen; be it supplements and fertilizers from B.A.C or I recommend you order from Amazon, the brand Cultivers, concentrated kelp solution (Ascophyllum nodosum) which, for example, at a ratio of 5ml/L is fantastic nutrition to spray on your plant - you don't need to spray a liter on the leaves - with a couple of sprays from your spray bottle, kelp is incredible for correcting deficiencies, providing nitrogen, balancing the integration ratio between phosphorus and magnesium especially during flowering, and if your grow, for example, shows stress from excess lights, excess nutrients, and others, it is also very important as a probiotic to prevent you from getting any less thought-of pests - be it soil fungi, like the dangerous Fusarium or on leaves, the Mildew. Very important, leaf watering should not continue once you have developed buds, and when you are in that phase, everything you give to the grow should be in the soil, and always remember to try not to do it with lights - be it sunlight or grow lights, because water on the leaves with the lights has a magnifying effect and will burn the leaves. I hope my advice clarifies how you should do your watering and more your prior preparation of your grow medium, which will be crucial for the success of your grow. May God Jah protect you, and may this grow (I don't know if it's your first) turn out wonderfully. And if you want, add me or your follow-up to my area and my diaries, as I always provide very important information to new brothers starting in this cannabis growing thing. 420 Always!!!
