How often should I be watering?Growing in coco per...

Yeah man every other day works for my coco grows in 25L pots , by this time they have dried out and are ready to go again. Some of the larger autos ( 12oz plus) will want a feed and water every 24 hours for that mid to late flower stage . Like old mate was saying water until it starts dripping out the bottom

soilless with hydro nutes? (hyrdo nutes just means it's 100% soluble and chelated for immediate plant use.) If so, you fertigate every single time and get 10% runoff (down drain or toss it outside), religiously. This maintains a consistent, fertile rootzone (no buildup). 1,3 to 1,5 EC for a mature plant. ratio of nutes may need slight adjustment from vege phase to bloom phase, but nothing as drastic as often advertised. you still have to dial in ratio of nutes given, but soilless is one of the simplest things. Wait for that top layer to change color and fertigate. rinse and repeat. if you do this at same loss of weight from pot, it'll require same volume of water to get 10% runoff. you can work backward from there to dial in how much fertilized water to mix up. You can re-fertigate sooner, but i'd wait for top layer to dry (slight change in color makes it obvious). If this results in any droop or wilting due to pot being too dry, obviously fertigate sooner. a good wet/dry cycle, especially early on, is very beneficial. promotes root growth, reduces superficial roots, and reduces risk of root zone issues.
